Dr Koo is very and polite. Nice to see someone who wants to get on the issue right away instead of messing around. The wait time was very short and quick..

The surgery went smoothly, and my recovery has been excellent. Dr. Koo is a skilled surgeon who truly cares about his patients. I highly recommend him.

Dr. Koo was friendly, knowledgeable, explained things well and certainly asked if I had any questions. He becomes highly recommended and his ratings are good!

Dr Koo was friendly and checked to see how my shoulder recovered from surgery. He also answered all my questions to my satisfaction

I went and got my labral repair with Dr. Koo in January of this year, and it was an amazing, smooth experience. I had been suffering from pain for about a year, and from the consultation to surgery day him and his staff were so kind and accommodating. He is extremely kind, which I very much value in any medical professional, and listens to your concerns. Additionally, his PA Laura mirrors those qualities of empathy and kindness. Labral repairs are one of his specialties, so I felt comfortable right off the bat, and surgery day was easy. I also have Ehlers, so I was a bit worried, but he took this into consideration. Aftercare instructions were thorough, and I felt cared for throughout the whole process. Now at about 4/5 months past the procedure I’m doing so well, I have all of my range of motion, and am steadily regaining my strength. I am so grateful to him and his staff for helping me get my life back, cannot recommend him enough.

Was able to squeeze me in for what I self diagnosed as major trauma. It may turn out to be that, but nice to get in quickly and have a good discussion and gain understanding of how it may play out and also to rule out some initial concerns.

Dr Koo was on time and was very thorough and efficient with his evaluation of my problem. His recommendations were understandable and helpful. Very personable in his manner. The result of my surgery has been excellent.

Was able to diagnose and treat my issue quickly. I'm feeling much better- without surgery!

Always on time and willing to answer any questions!

Excellence in evaluating conditions, MIR results, past medical history in formulating options and perspectives. Always impressed with the team at ProOrtho.

Excellent, got in before appointment time. Dr Koo was very helpful.

Dr Koo is an attentive listener and very knowledgeable. He presented options, and gave me time to ask questions. I feel confident in his ability and judgement to provide all the necessary information to aide me with my decisions about how to proceed with my care.

Doctor is very knowledgeable, and great people skills. I will come back to him for any injuries

Finding ProOrtho and Dr. Koo has been a wonderful experience.

Dr. Koo is an excellent communicator with great bedside manner.

It was pretty Koo

Professional and confidence-building. Very kind, not condescending. Efficient. Excellent! Outcome is yet to fully be determined, but therapist says I’m on track for the amount of work done👍

Dr. Koo is phenomenal. He fixed my shoulder after 20 years of pain from college swimming days. It now functions better than when I was in high school and I am now 43, competing on it again without pain. Thank you so much!

Outstanding experience, knowledgeable and efficient staff, modern facility.

My questions were answered and my concerns taken seriously

Dr. Koo actively listened to my questions and concerns and provided the guidance I was looking for, including procedure tasks and benefits. His prfessionalism is outstanding. I left the office confident I had chosen right surgeon to review my case.

Very pleased, great personal!

When I thought I might need shoulder surgery I really did my homework! I chose Dr. Koo based on what I learned. I don't think I could have made a better choice. He fully explained why I needed a shoulder replacement and answered all my questions. He's an EXCELLEMT surgeon! BONUS, he accepts Medicare as do the anesthiologists he uses. He was specific as to what my physical therapist should do during my recovery. His PA-C Claudia Kalotay is also exceptional.

Excellent experience. First appointment. My questions were answered and I am feeling good about going forwared.

Outstanding surgeon and staff

It was a pleasure to work with Dr. Koo who cleaned up my rotator cuff injury fixing three associated tendon tears! He is an excellent surgeon. I nursed the injury for a year before having surgery. Now, five months post surgery I am able do almost everything with very limited pain and almost full range of motion. It’s still healing but feels 95% better that it did after my fall in the snow!

Great team ready and extremely knowledgeable.

Dr Koo was helpful and is a skilled doctor. He replaced my left shoulder and I haven’t had any issues with it. It continues to get stronger with exercise. I’m expecting the same will be true on my right shoulder.

My experience with Dr. Koo has been great so far. He really explained my situation in depth and let me know what my outcome is. So cannot wait to get on this healing track to recovery and have surgery to fix my shoulder.

I began to see Dr. Koo almost three years ago due to a shoulder fracture complication and rotator cuff problems. Dr. Koo has become a reliable ally in my shoulder journey and both he and his staff are supportive and knowledgeable. My rotator cuff became problematic during Covid and I was one of the first day cases when the surgery center re-opened. I was well looked after, from intake to the surgery itself, to after care. I was fitted for my sling before the surgery, which gave a chance to figure out how to get into it before the day--a small detail that was very helpful in the long run. About 18 months later the fracture complication needed to be taken care of. Dr, Koo recently did a reverse total shoulder replacement and once again, I have been well taken care of. Given the nature of this surgery, pain management was important and it has been well addressed. Dr. Koo knows his way around complicated shoulders and has really helped my recovery from previous injury and complications. Appointments have been easily available, MRI scheduling has been efficient, and I have rarely waited more than a few minutes for appointments. Highly recommend.

Had 2nd shoulder surgery by Dr. Koo earlier this year. I was about to give up. However, attending one of his info sessions convinced me to schedule time with him. Within the first few days from surgery, felt so much better. Now, 6+ months later, definitely know that I have properly healed, and so ready to resume my active lifestyle. Can't thank Dr. Koo, Claudia, and all of his staff enough!

I had a total reverse replacement on April 30,2021. I was in the hospital for 5 hours and then discharged. Dr. Koo and Claudia the Anesthesiologist were excellent. Post Op visits were great. If you need surgery you couldn't find anyone better.

great people, fixed me up great, everything went exactly as the told me it would. nice, great service, professional, and knowledgeable staff all the way through

The staff has been very interactive and professional. My appointments have always been on time. There have been no issues with my surgery or recovery. I would definitely recommend.

Didn't have to wait long for an initial appointment and once here they always get you in early so don't be late. Surgery was very accommodating for me personally. I really appreciated the extra effort that was put in to make me feel at ease. I would defiantly recommend anyone with a shoulder injury to make an appointment with Dr. Koo and Claudia.

Dr. Koo and Claudia, PA were wonderful at repairing my torn rotator cuff. They were even able to avoid cutting my tattoos! lol They are their staff were warm, available, and efficient. Having surgery at an outpatient center was much preferred over going into the hospital. It was fast and easy for my spouse who picked me up afterward. If I ever need orthopedic care again, I'd go back to Dr. Koo and Claudia!

I recovered as expected and had easy and quick service throughout the surgery and recovery

Dr. Koo, Claudia and their staff were very helpful, kind, thorough and patient. I'm please with the care that I received for my shoulder injury, surgery, and the outcome to date. Thank you!

Surgery with Dr. Koo and his assistant, Claudia, was a great experience. Everything went exactly as planned.

Great experience, staff is friendly and very helpful. Couldn't have asked for better treatment!

Dr. Koo is fantastic and I enjoyed talking with him every time I had the chance to. I was totally confident going in to my surgery, and I don't think it could have gone any better. His assistant Claudia is great to work with too, and I feel as though I am in great hands when I am here. The rest of the staff is wonderful as well.

My husband had a complete shoulder replacement surgery done by Dr. Koo and his surgical assistant, Claudia in early December. The surgery went very smoothly and recovery went far better than we had anticipated. In fact, my husband only took prescription pain medication for two days. The recommended ice machine was very helpful! It has now been 5 months, and he has full range of motion and virtually no pain - what a relief! Dr. Koo's office in Kirkland is run very efficiently; we've always been seen promptly at our appointment time. All of my husband's after-surgery appointments have been with Claudia, who is very kind, knowledgeable and helpful. If you need shoulder surgery, I highly recommend Dr. Koo.

I'd been having shoulder issues for years. I got an MRI and Dr. Koo diagnosed me with a Torn Labrum and floating cartilage in the shoulder, recommending surgery. I'm 3 months past surgery and feeling great. I have no remaining pain in my shoulder and am quickly regaining strength. I've recommended Dr. Koo to several friends and coworkers with shoulder issues.

I came to Dr.Koo's office after having already seen on Dr in Renton at Valley medical center's Proliance. I was not satisfied at all with my Dr. in Renton and wanted a second opinion. I was treated respectfully and believed about my condition from my very first appointment. I had a MRI done and it was noted that I had a SLAP tear in my right shoulder. Physical therapy was advised but when the pain persisted even after a cortisone shot the decision was made to move forward with therapy. I was extremely happy with the results after surgery and I am back to work full time now. I would recommend Dr. Koo to anyone with orthopedic needs He is awesome! His PA Claudia has also been there for me every step of the way and for that I am very thankful! She never hesitates to answer any of my questions and is very prompt with filling out all the paperwork that I needed for work. I want to thank them both for being so awesome!

Very good at getting right down to what they need to fix, did everything perfectly. Gave me a solid plan to follow to get me back too 100% as fast and safe as we could. All around a solid experience.

The entire staff was amazing. They were very clear with their process and procedures when I had my rotator cuff repaired. Would recommend anyone needing shoulder surgery to use Dr. Koo!

Best care and service!!!

Dr. Koo and his team at ProOrtho are experts, professional and all around deliver outstanding patient care. They have always answered all my questions and then some. This made all the difference making the decision to have surgery and then understanding my progress post surgery. They also referred me to a phenomenal Physical Therapist who listens and works with me to achieve my goals. Big Shout Out to the team for all the good work they do.

Dr. Koo and Claudia are amazing surgeons. With minimal downtime and nothing but support with the entire office. I would recommend them to anyone. Best in the business!!

From start to finish- Excellent experience, professionalism and amazing staff- Highly recommend. Also- appointments all on time !

I'm very thankful for the care, experience, and professionalism given by Dr. Koo and Claudia at ProOrtho. I experienced a serious shoulder injury last ski season with massive tears and was seeing another physician by a different provider. My therapist recommended Dr. Koo and Claudia. The surgery went very well, pre-op and post-op care by Claudia was great. I can't express enough how thankful I am for being under their care. I would not be the person I am today if it weren't for them. I have full range of motion and strength is coming back. No issues. If you have a similar injury, you owe it to yourself to be seen by Dr. Koo and Claudia.

I was recommended to Dr. Koo for surgery and was very happy with my initial visit, as well as the surgery that followed. His surgical team was very professional and had great bedside manner, which is important to me. I would highly recommend Dr. Koo.

Follow-up visit with Claudia. She was thorough and reassuring as to next steps.

Dr. Koo and Claudia Kalotay are amazing. I highly recommend them both to perform Rotator Cuff Surgery, Subscap repair, and Biceps Tenodesis. I give this team a strong 5 STAR!!!!

I had a fantastic experience working with Dr. Koo and his team! I didn't have any strength with my right arm due to a torn labrum in my shoulder, and now after surgery and rehab I feel back to normal! I would strongly recommend Dr. Koo, Claudia, and staff for any shoulder issues you might have!

Dr. Koo and Claudia Kalotay, PAC have helped immensely in the management of pain from my shoulder injury. They are genuine and listen to me. I appreciate their thoughtful care plan. They are also good human beings - I really recommend getting care from them! Wendy

Dr. Koo and ProOrtho have been beyond excellent for treating my shoulder issues from Ehlers-Danlos Syndrome (EDS) Hypermobility Type. Having already had a repair before, I was concerned my left shoulder after tearing might not be able to be surgically repaired again. Luckily, I had been a patient of Dr. Gregush from both my hip surgeries with Pro Ortho in the past few years, that were both life-changing and hugely beneficial. Knowing of my EDS, Dr. Gregush mentioned Dr. Koo and I couldn't have been luckier to find this Shoulder Surgeon Expert. Dr. Koo is an absolute professional, compassionate, understanding of EDS and Hypermobility, and very skilled surgeon. Not only was I able to avoid needing a graft for my shoulder repair, but Dr. Koo was able to repair my shoulder entirely so that it is more stable, less painful, and stronger for my future. Everyone at ProOrtho has been so understanding of my unique case having Ehlers-Danlos Syndrome, Postural Orthostatic Tachycardia Syndrome, and Mast Cell Activation Syndrome and gone above and beyond to ensure my comfort and safety throughout this process; as a 'complicated and chronic' patient this has meant the world to me to feel so well cared for and listened to. I cannot sing enough praises for Dr. Koo, Claudia Kalotay PA-C, and ProOrtho; thank you for restoring so much of my life back to me-I am so thankful and grateful to be a patient and have had the incredible treatment and support of ProOrtho and my doctors here.

Dr Koo chose to repair my shoulder injury when several other highly rated doctors would not. I had a biceps tendon tear, a rotator cuff tear and a subscap tear. By all accounts my shoulder was in bad shape I traveled over 2000 miles to see Dr Koo. I was able to accomplish some pre-screening with Dr Koo and his staff. My first appointment was prompt, informative and very encouraging. I scheduled surgery and from the time I arrived until I was leaving in my car with my wife there was less than 5 minutes of idle time. I did not feel rushed at all, things were moving at a very efficient pace. My post op appointment was equally pleasing, no delays, very informative and very helpful to my recovery

Amazing team, the best I've experienced.. The patient care is most important thing. I'm glad I picked this group. Would highly recommend.

Dr. Koo is one of the best shoulder surgeons in Seattle. As a PT he has the best outcomes.

I want to express my sincere appreciation for what Dr. Koo has done for me. To think how close I came to not going through with surgery. I was doubtful but a trusted physician told me if anyone could fix my shoulder it would be Dr. Koo. I had such bad luck with a knee replacement I was afraid of another disappointment. Dr. Koo went above and beyond to even call me from Hawaii to reassure me. I am so pleased with my recovery. Dr. Koo is truly a gifted surgeon. I can’t thank him enough. His entire team is great to work with also.

Extremely happy with appointment. Dr Koo is super professional.

This was our first visit with Dr Koo and it went very well. All of questions were answered and a plan was set

Dr. Koo understood by concerns. Help me understand my next steps. Explain that there's no rush for surgery if by shoulder is progressing slowly on its own and that physical therapy should help.

I have total confidence in Dr Koo

Positive attitudes & information shared about the process.

Quick in and out even thou the news wasn’t good I already had a feeling in was bad Definitely recommend him.

Everything is going as planned in my reverse shoulder replacement. If you need shoulder repair this is the Doctor. Prior and after my surgery he was very responsive to my numerous questions. He also has a great staff. Follow up 2 years later. Still doing good. No pain and good range of motion.

Excellent visit. Staff and doctor were awesome!

Doctor was on time, had reviewed my chart, and his assistant Brianna was just returning

Excellent visit with Dr. Koo!

Dr Koo has great knowledge of his specialty as well as being a very good listener. He made me feel very confident that what he was recommending was the best option available.

Excellent at every level!

Dr Koo is pretty cool... I look forward to my next visit

Great experience with Pro Ortho and Dr. Koo. Pre op and post op staff were excellent and Dr. Koo and his team were also great. Most importantly, I felt immediate relief from the pain I had been experiencing. One week from surgery and shoulder feels great.

Dr. Koo did a great job educating me regarding the pros/cons of the different options available to me. After that, he was very supportive of the choice that I made.

Nice to meet the doctor for the first time. He was happy to answer my questions.

Very smooth process from scheduling to arrival, from the surgery PreOp and the PostOp process - overall a very good experience!

Great visit. They listen, are professional and right on time. Much appreciated.

Dr. Koo and his staff, epitomize the word “professional”…. and visiting the clinic is a pleasant experience.

When I thought I might need shoulder surgery I really did my homework! I chose Dr. Koo based on what I learned. I don't think I could have made a better choice. He fully explained why I needed a shoulder replacement and answered all my questions. He's an EXCELLENT surgeon! BONUS, he accepts Medicare as do the anesthiologists he uses. He was specific as to what my physical therapist should do during my recovery. His PA-C Claudia Kalotay is also exceptional.

Dr Koo is an exceptionally skilled and caring Surgeon who specializes in Shoulder repair and treatment. His years of professional experience and calm demeanor were huge factors in choosing him to do my shoulder replacement surgery. He takes the time to answer any and all questions, and was reassuring and accurate in providing information. When I had concerns post op re: pain, he listened calmly and ordered X-rays to evaluate the situation. When all turned out fine, he remained thoughtful, caring and encouraging. At all my appointments, he arrived promptly, and his very kind staff, Jennefer & Gemma, also provided helpful information, answered emails and calls as promised. This is quality, patient focused care, and I highly recommend this team if you need shoulder surgery.

Dr. Koo is a gifted surgeon with kindness, caring and charm. I highly recommend him.

I had a left shoulder replacement, and it has been amazingly good so far. A week after surgery, I use a little codeine at night only, and have unbelievable range of motion already. If my right shoulder ever gives me any problems, I wouldn’t hesitate at all—I’d go straight back to Dr. Koo. Talented, compassionate, and professional. Has a wonderful staff as well!!

The entire office staff has been extremely helpful. If I had any questions or concerns they get back to me really fast. The team seems to be very efficient

Dr. Koo has performed two shoulder replacement surgeries with me. I cannot express the confidence I have in his skill and follow up! I had my second follow up today, with no complications and physical therapy bringing more greater responsiveness to my arm! Claudia and Gema are both great assistants and resources for any issues.

I've had great shoulder results with Dr. Koo and all his staff.

Had Rotator Cuff surgery 5 weeks ago and it has been a smooth recovery. Rotation coming back great. Love the team.

Shoulder replacement was a success. Healing good, time will give a full recover!

Dr. Koo performed surgery to repair a badly broken clavical and it could not have gone more smoothly. After 8 weeks I was more-or-less fully recovered with full range of motion in my shoulder and no issues with any of my soft tissue or nerves and trending well ahead of projections from PT. Could not have gone better!

I came to Dr Koo because I already knew how excellent, thorough and kind he is, based on my brothers very successful surgery. He is as great as ever and now has a wonderful PA, Claudia, who is also outstanding. I am very active and am pretty much 100%, a few months early. Thank you both and to the whole team!

Dr Koo and super-PA Claudia have provided excellent care to repair my injured shoulder (torn rotator cuff, turn bicep tendon, bone spur). The surgery itself went smoothly and the after-care has been fantastic. Highly recommended.

I was suffering with shoulder problems over last 4 years and had one failed surgery 2 years back. Had lots of pain, stiffness and limited range. So, was a bit worried this time but Dr Koo ,Claudia and entire team of ProOrtho have been amazing. They are very prompt in responding and co-ordinated with PT so efficiency. There is no pain after the surgery. I was back my normal energy level in a week. 8 weeks PO, I have started active motion with hardly any pain. Shoulder never felt so good over last few years. 🙏 Thanks to Dr Koo and Claudia

I've been dealing with shoulder pain for the past couple of years. I tried everything short of surgery. Finally I met Dr. Koo and he is the best! He reassured me and gave me confidence that, with time, I would be recovered and back to normal. I am 4 months out form surgery and doing really well. It is a slow recovery, but Dr. Koo set realistic expectations and has been great all along the way. His PA, Claudia is amazing to work with and the two of them are a dynamic duo. Thank for getting me back to my hobbies and helping me get back to throwing the ball in the backyard with my daughters.

I recently had my shoulder surgery with Dr.Koo. I highly recommend Dr.Koo. The surgery went smoothly, post-surgery, I had few days that I had pain but after the pain gone and I can move my hand quite well. They billed me to the reasonable amount. Additionally, Dr.Koo's team sent a nice thank you note with a gift-card thanking me for doing my surgery with them.

Dr. Koo, his PA Claudia and support staff are the best. They took great care of me throughout the entire process. I had rotator cuff surgery 5 months ago, and am well on my way to full recovery. I would highly recommend Dr Koo.

I was referred to Dr. Koo and Claudia (his amazing PA) by a friend of mine Dr. McCutchen. I was hit by a truck while riding my motorcycle home from work and my shoulder was torn up inside. They reattached my labrum, bicep tendon, and my supraspinatus. They also took care of the the frozen shoulder I had due to my accident. They did a wonderful job and I would see them again if needed (I truly hope that I never have to). I saw Claudia for all of my post-ops and she is the absolute best!!

Great prep, surgery and 7 months of follow up fir the type of surgery I required. The results I expected. Would highly recommend.

Elite expertise and caregiving. From Dr. Koo's intake & surgery to Claudia's considerate direction, I have felt like a top priority at every turn. Best of all - shoulder (had RC & biceps tendon repair ~3mo ago) pain-free and getting stronger every day. Grateful for their time and talent.

Dr Koo and Claudia are great!

This is the most amazing place ever! I have had two shoulder replacements. Between Dr. Koo, Claudia, and Gemma I have experienced nothing short of a miracle. I have had NO pain, my recovery has been uneventful and this place is now like my family. I HIGHLY recommend Dr. Koo, and shoulder replacement surgery! They have all made my life so liveable! Thank you all! xoxo

Dr Koo, Claudia, and their staff have been great. They answered all my pre-surgery questions and walked me through what the recovery process would look like. No complications so far.

Dr Koo surprised me. I was scheduled for a reverse on my shoulder but Dr. Koo saw that my problem wasn’t as bad so he did a regular replacement that gave even better results. I have had many surgery’s and this was the best experience I’ve ever had!! Thank you Dr Koo

I have had a very good experience. Claudia and Dr Koo have provided me with a great service. I have little pain any more and mobility is better than I expected pre-surgery. I hope I never need to use your services again but I would not hesitate if needed. Thank you

I specifically searched for an experienced surgeon who specialized only in shoulders. Samuel S. Koo, MD, MPH, was the physician I wanted to perform my total shoulder replacements. He is excellent. My physical therapist is so impressed with the results, my range of motion, small incision, and lack of pain. Claudia M. Kalotay, PA-C, his physician assistant, is equally excellent. Gema, their medical assistant, and the radiology staff are pleasant and efficient. I am very grateful for their superb care.

Awesome staff, great outcomes! Saw Dr. Koo and Claudia for my shoulder, which needed a repair. I've trusted them all along, and have had nothing but progress and good experiences. Highly recommend to anyone who needs consultation or surgery for shoulders injuries.

Dr. Koo and Claudia were instrumental in restoring my shoulder to normal. I completely trusted their expertise during my surgery and post care. They answered all my questions with patience and knowledge. I would easily recommend them to anyone seeking rotator cuff surgery.

My experience in working with Dr. Koo & Claudia has been terrific. They are both very attentive, responsive and thorough. I have already recommended them to a few friends who are in need of shoulder care.

Have had good success with graft surgery on my right shoulder. Hoping to delay total shoulder joint replacement and has been 2.5yrs since surgery. I have been able to swim, workout and play golf. None of which I could do prior to surgery.

Dr. Koo, Claudia and all the Ortho team are the best there is. Have repaired both my shoulders and it could have not gone any better. Everyone is very friendly and really care personally about their patients individual needs. If you have to must shoulder surgery I would recommend them without reservation!

Dr. Koo & team have been great throughout the whole process.

I have had two shoulders repaired by Dr. Koo. It has been five years since the first and am currently rehabbing the second. Dr. Koo is a fantastic man and surgeon. His competence is clear and has a very friendly and helpful demeanor. I have looked at many other surgeons before deciding to trust Dr. Koo with my care and can say choosing him was one of the best decisions of my life. Both surgeries were a complete success, and I have had no complications post operation. I am very fortunate to have found Koo and his team. The whole experience was enjoyable. Me and my family were treated like a part of his. I hope others get to share my experience. Thank you Dr. Koo.

Currently in Week 6 of Bankart repair and Remplissage procedure. Very happy with the results so far!

Awesome experience, wonderful staff and follow-up. After a massive rotator cuff tear, I did not have much hope for a full recovery. Ten months later, still doing physical therapy but am so pleased with the progress. I hope to be golfing again soon. I cannot express how much I appreciate Dr. Koo's knowledge, experience and compassion -- not to mention his and Claudia's incredible surgical skills. I know he was able to repair something that I doubt most other physicians could have accomplished! Again, many thanks to his entire team for restoring my shoulder function and allowing me to resume nearly all of my former activities.

Dr. Koo and his assistant, Claudia, are amazing. The level of knowledge of the shoulder, the post-op care and the "real" conversations about the procedure and what to expect set them apart. Highly recommend checking them out if you think you're in need.

Dr.Koo and his team always take good care of me. They give me advice and follow up with my health concerns. They are very friendly. I would recommend my friends to see Dr. Koo to get the best care.

Excellent care for a torn shoulder tendon. Easy surgery.

On Feb 6, 2018 I had a total left shoulder replacement, with 90% cartledge loss and grade IV arthritis. The shoulder of a 90 year old for a 60 year old. Anyway, Dr. KOO is known to other doctors as a troubled shoulder specialist, and I got referred from Dr. Igor Uritsky to see him. My ROM is perfect, like when I was in my 29s. I have no pain. I was told how bad replacements were and this experience was awesome. I know every person is different, but I cant sorak highly enough about Jennefer, Claudia and Dr Koo! Thank you!!

Dr. Koo and PA Claudia worked on both of my shoulders. My right was a total reverse and my left was a really bad cuff tear. Each surgery was easy for me and pain was always minimal. They took me from a life with no working arms, and always pain, to a life with no pain at all, and I workout my arms daily with no restrictions, and NO PAIN. Dr. Koo told me that he couldn't do it without Claudia's helping hands. A wonderful team, and I highly recommend Dr. Koo to anyone with painful non-working arms.

I had a rotator cuff done on me by Dr. Koo. I had a great and professional experience during the pre and post operation stages. The surgery was very well planned and operated. I'm doing very well in my recovery. I recommend Dr. Koo as a shoulder specialist.

Dr. Koo reattached my biceps after another surgeons shoulder repair left me deformed, hurting and scared. Dr. Koo made me feel confident that he could fix the problem, and he did. Recovery was fast and almost pain free. 2 years later my arm is without any pain of disability.

Dr. Koo is highly skilled, kind, and caring, accessible and concerned. Other medical professionals think he is top of the line, and they are right.

My visit was fast, professional, and very helpful.

Brief visit. Thoroughly explained my condition and addressed my questions well.

Great experience.

Always great!😊

Dr. Koo repaired left and right shoulders after years of abuse. range of motion 100%. My aftercare was followed to the T and my reward was full use. There is nobody better.

All questions and concerns answered satisfactorily.

I found Dr Koo to be very knowledgeable and communicative. I went looking for advice and quickly felt that I had received sound advice!

My experience was great! Dr Koo is an incredible Dr and his team took care of me with great care.

Always prompt, efficient staff, kind and respectful. The whole experience for my shoulder replacement has been positive.

I had a left shoulder replacement, and it has been amazingly good so far. A week after surgery, I use a little codeine at night only, and have unbelievable range of motion already. If my right shoulder ever gives me any problems, I wouldn’t hesitate at all—I’d go straight back to Dr. Koo. Talented, compassionate, and professional. Has a wonderful staff as well! 12/11/25–My shoulder works great! Two and a half years later, I could not be any more pleased with the results of my shoulder replacement surgery. Best decision ever.

I am very satisfied with the care that I have received here. Prior to my surgery I was told what to expect and what I was told has turned out to be true. I am glad I had the surgery and I am glad I came to this clinic to have it done.

Dr. Koo and and his staff are friendly and efficient. I have had shoulder replacement surgery, came through able to move pain free. So appreciate all the good he does.

Dr Koo is great at understanding what progress I am completing.

Dr. Koo is truly one of the best shoulder surgeons He repaired my rotator cuff at the end of February, and I couldn’t be more pleased with the outcome. Nearly four months later, I’ve regained about 85% of my range of motion and strength, and I continue to improve. I also have only three tiny scars—such precise, skillful work. Before surgery, even after five weeks of physical therapy, I could barely lift my arm. As someone who’s very active—practicing yoga, strength training, Zumba, and skiing—that was incredibly frustrating. Now, I’m back to all my gym activities and slowly regaining full function. Recovery is still ongoing, but the progress has been remarkable. Dr. Koo and his entire surgical team were not only highly professional and skilled but also kind, friendly, and even funny, which made a big difference during a stressful time. I’m deeply grateful for the excellent care I received and highly recommend Dr. Koo to anyone in need of shoulder surgery.

Appointment was on time, complete, and as expected.

Dr. Koo did my rotator cuff surgery — and did a remarkably good job. I healed quickly and extremely well, and five years later the repair is still in excellent shape.

Super experience. Great doctor!!!

I’m very happy with my shoulder surgery. I am improving every day. I would recommend Dr Koo to anyone that is looking for a superior surgeon.

Great visit; concise but will elaborate; knowledgeable, speaks clearly, caring, listens and responsive.

Attentive. Encouraged to ask questions.

He was very good. Answer all my questions

Efficient in diagnosis and next steps.

Wonderful physician. Great knowledge and understanding.

Very professional and down to earth. Good communication with clear options avaliable

Surgeon was very good at communicating and took time to answer all questions. Surgery center staff was professional, friendly and efficient. Procedure went as scheduled and the results are good so far.

I was referred to Dr. Koo by my PT when I needed surgical repair of a rotator cuff tear. I have hEDS and Dr. Koo is experienced treating patients with this condition, which can be tricky when it comes to surgeries. He explained things clearly, answered all my questions, and expertly repaired the full thickness tear. The PA that I saw for most of my follow ups is fantastic, and I just saw Dr. Koo today for my one year check-in. Happy to report that I’m very satisfied with the results.

Good advice, efficient, practical. I will go back if needed.

Tuve mi cirugía con el Dr Samuel Koo y fue todo un éxito mi cirugía es un excelente médico en cirugía del hombro lo recomiendo al 100 %

Dr. Koo is a kind, professional doctor. He fixed both of my shoulders and I recommend him to everyone.

Dr Koo always prompt, and professional.

Just had shoulder surgery this morning and it was a great experience with Dr.Koo!

Very professional and trustworthy 👍

I only met Dr Koo one time for my initial visit prior to surgery. He was likable, courteous, and patiently answered my questions. Ask me again after surgery. :)

The office of Dr. Koo he & all staff treated me very well. I am still in recovery so I don't yet know how range of motion will be. But they are dedicated & so far caring & competent & answer questions promptly.

The entire office staff has been extremely helpful. If I had any questions or concerns they get back to me really fast. The team seems to be very efficient. I just had my one year check up. Dr. Koo did a great job on my shoulder hardly any scar.

I had a good experience at P roliance with Dr Koo. Everyone was very friendly and my visit was handled efficiently.

This doc was really good!!! Listened to me patiently, answered very clamly and patiently. Didnt just touch and go. Performed xrays to arrive at a firm opinion vs the previos doc at the same place that I has gone to. He is my go to doc incase something with my bones happens. Thanks Dr Samuel.

Dr. Koo is a wonderful physician who is a true professional and is surrounded by knowledgeable, caring, and friendly staff!

Dr. Koo was recommended to me for shoulder surgery. We live in Eastern WA and made several trips over Snoqualmie during snow storms. Due to the extent of repair, I was on a slow protocol and spent 9 months in PT. But... All of it was so worth it. I have been able to resume all my activities with no shoulder or related area pain. I highly recommend Dr.Koo. Thank You Dr. Koo and all of your staff.

I have been using this surgery center for many years for various orthopedic repairs. I have always had exceptional care and results. My first experience with Dr. Koo and staff was no different. I liked the fact that they take the time ( including the anesthesiologists) to explain things so you know what to expect.

From pre-op to post-op and recovery, it could not have gone better. Dr. Koo, Claudia, and the Pro-Ortho team made it a seamless outpatient experience. Thank you to all, it is wonderful to be pain free.

The place is very nice and easy to work with. My pre, surgery, post and on going service has been great. I would recommend if surgery was needed for shoulder.

Dr. Koo and his assistant are great. I felt in great hands.

Surgery went very well. Recovery on schedule and will be back golfing six months after surgery! Great job. After one year, back to normal, hitting the ball further.

I had been suffering shoulder problems for over 6 months when I was referred to Dr Koo by my physical therapist. I was seen, MRI'd, explained my situation, and surgery scheduled within three weeks. It was amazing to get a diagnosis and treatment plan so quickly. Dr Koo explained it all to me, answered all of my questions, and made me feel so confident in what our plan was. Claudia, his assistant dr, has been doing all of my post surgical care and she is also wonderful. I love Dr Koo & his team!

Dr. Koo and Claudia have done work on both my shoulders with great success. No complaints and I'm glad I got them treated earlier than later. Great communication and service!

I highly recommend Dr. Koo and his team. I had total shoulder replacement this Spring and couldn't be happier with the results. I found Dr. Koo and Claudia Kalotay PAC, to be very caring and extremely competent. I appreciate that they were always on time with appointments. The surgery was done at the hospital and I was home the same day. The post surgery follow up and support has been excellent.

Dr. Koo, Claudia and the entire staff at ProOrtho have been outstanding to work with and have exceeded my expectations in every way. The staff the day of my surgery and the rest of the team in the operating room were great and did everything they could to put an, admittedly, nervous patient at ease. Two months after surgery my shoulder feels better than it has in 5 years and is only getting better. It’s a pleasure to work with such a great group of professionals, I can’t recommend them highly enough.

Dr Koo, MD and his PA Claudia performed surgery on me recently after an MRI showed serious tears in my supraspinatus tendon, my infraspinatus tendon and my bicep tendon (the Bermuda triangle of shoulders). The experience has been great on all accounts. They're scheduling is so buttoned in a manner that I've never seen before in a doctor's office. I've never had to wait more than a few minutes for appointments, etc. and surgery and post-surgery expectations were explained well - with no surprises. And so far at the 12 week mark my shoulder is coming along nicely and I'm so happy at the rate it's healing. Now I just have to continue to put in the work! I definitely recommend this team if you need shoulder surgery!!

Top notch care and after treatment!!! I highly recommend Dr. Koo for any shoulder issue have!

I was referred to Dr. Koo and Claudia (his amazing PA) by a friend of mine Dr. McCutchen. I was hit by a truck while riding my motorcycle home from work and my shoulder was torn up inside. They reattached my labrum, bicep tendon, and my supraspinatus. They also took care of the frozen shoulder I had due to my accident. They did a wonderful job and I would see them again if needed (I truly hope that I never have to). I saw Claudia for all of my post-ops and she is the absolute best!!

My shoulder was in terrible shape. The surgery was definitely worth it and my shoulder is doing wonderful after the surgery and physical therapy. Thank you very much

Elite expertise and caregiving. From Dr. Koo's intake & suregery to Claudia's considerate direction, I have felt like a top priority at every turn. Best of all - shoulder (had RC & biceps tendon repair ~3mo ago) pain-free and getting stronger every day. Grateful for their time and talent.

Dr. Koo and his assistant, Claudia, were fantastic! 10 stars out of 5. Surgery went perfectly and rehab went well and successfully. I am 12 weeks out now and have great range of motion and have never had any pain (as opposed to constant pain before surgery). I recommend him highly if you want a great outcome in a shoulder replacement.

Dr. Koo and his assistant Claudia have now replaced both my shoulder joints with a new artificial joint. Both times the preparation process, surgery and recovery have been better than I could have hope for. While recovery is somewhat slow, both shoulders are working fine and I am out of pain on both sides. I can highly recommend Doctor Koo and his team for their excellent service and care. I appreciate having top notch medical professionals helping me out of pain and on to a better life.

Working with Dr. Koo and Claudia was an excellent experience! My shoulder surgery turned into requiring quite a bit more repair than the MRI showed. Dr. Koo made thorough and lasting repairs. Claudia provided clear direction for post surgery activity and requirements. I'm extremely happy with the surgery and progress to date!

I have a torn rotator cuff, everybody involved was absolutely brilliant(Dr. Coo, Physician Assistant Claudia, Anesthesiologist, etc..). Surgery was textbook perfect, recovery and PT have been thankfully uneventful and good.

the whole experience was wonderful. Everybody was very helpful. Claudia was a god send of support and comfort.

28 year old and had a Rotator cuff repair with Dr. Koo September 2019. 6 months later no more problem with the shoulder and it is feeling great and i'm close to getting back to the sports I loved. Dr Koo and Claudia are both super professional and great at what they are doing. They not only identified problems clearly, perform an excellent procedure and really focused on post-op care so that I can get the rehab I needed. The post-op follow up were key to my recovery as that helped me regain my range of motion and strength quickly. I couldn't recommend them enough if you need any sort of shoulder care. Thank you!

I experienced my 3rd shoulder dislocation in July 2019 and decided to get surgery finally after 3 years of a unstable shoulder. I heard Dr Koo operated on Seahawks players before so why not go with him. had surgery in September great staff and surgery was fast. great clinic!

Another great experience at Pro Ortho Kirkland. My shoulder joint replacement surgery came out better then I expected. Thank you to the staff a Pro Ortho.

Great results. I am very happy with my "new shoulders". Both Claudia and Dr Koo have been super to work with. I have no qualms in recommending them to anyone needing rotator cuff surgery.

I had a great experience with Dr. Koo and Dr. Kalotay for my reverse shoulder replacement. The surgery was effective and after care was attentive. They were very focused on getting my range of motion back, and I couldn't be more pleased with the results.

Dr. Koo and Claudia are great!

Dr. Koo and Claudia were awesome! I've been suffering intermittent shoulder pain for over 10-years and the last year it didn't seem to go away as usual. Was referred by several friends in the healthcare industry to Dr. Koo. He gave me a couple of treatment options and thoroughly explained the process for each choice. I chose surgery rather than prolonging the inevitable. The surgery and post-op follow-ups went extremely well. They make for a great team and I highly recommend Dr. Koo and his team.

Great surgery work and post-op advice

Dr. Koo is an incredible surgeon who improved my pain level dramatically. After my surgery, my shoulder feels stronger and I am glad I made the decision to choose Pro Ortho. The staff is incredibly kind and willing to answer any question pre and post surgery.

Claudia (Dr. Koo's PA) is super knowledgeable and awesome to work with!~

Dr. Koo and Claudia are awesome. I saw Dr. Koo for my right shoulder and couldn't be happier with the surgery and the care from him and his staff. He's truly a shoulder expert and I would highly recommend him.

Absolutely amazing experience. After 2 prior shoulder surgeries, Dr Koo and his team have me without pain for the first time in years. Really appreciate the knowledge and expertise.

got me in right away and fix my shoulder. Claudia and Hemma very professional.

After seriously dislocating my shoulder which required surgery, my personal physician referred me to "The best shoulder guy in the state". He wasn't lying. Dr Koo did a fantastic job on what turned out to be a more involved procedure than initially thought. I'm right in the middle of my recovery and can already tell things are going extremely well. Claudia Kalotay has been providing top notch post op check ups and all the folks at Pro Ortho have been wonderful. Highly recommend the professionals at Pro Ortho.They are fantastic at providing everything a patient needs to make recovery as smooth and painless as possible

Dr. Koo and his team was great! He explained the issue with my shoulder and explained the risks and probable outcomes of the surgery. It turns out I had a lot of repair needed and the surgery and recovery has been a success. I am still working to return to contact sports, but I have returned to everything else. Thank you very much for everything!

I went to Dr Koo for a shoulder injury. They found a torn rotator and bicep. The surgery went extremely well no issues at all. I followed their after surgery instructions I did everything they recommended. Recovery and physical therapy were excellent. I don't have any complaints. Pain was minimal. Dr Koo and his team are awesome.

I don't know how a person could receive better medical care than what I received from Dr. Koo and his assistant Claudia. They were both very attentive, caring and professional every step of the way. I would highly recommend Dr. Koo to anyone looking to solve shoulder problems.

Dr. Koo is fantastic. He did my shoulder replacement surgery and already in less pain!

Dr. Koo has been/ is always a keen balance of professional + compassionate. He has my utmost trust + recommendation – the BEST!
