Care Philosophy

I believe all surgeons should have two essential qualities: integrity and empathy. To me, integrity means treating each patient as if I were caring for my wife and children. Family is exceedingly important to me so you can be assured you will be well cared for. I will not recommend surgery unless all non-operative solutions have been explored and exhausted. Also, integrity means to offer the highest quality care currently available. I am an expert at arthroscopic (minimally invasive) shoulder surgery. The shoulder is an extremely fascinating joint with lots of moving parts. As such, injuries are common and often complex. Over the last few years, there have been dramatic improvements in the way we treat shoulder pathology. We are now able to perform most shoulder surgeries using arthroscopic techniques (small incisions) that are at least as good, if not better than, the open (larger incisions) procedures of the past. Having trained with the world's expert in minimally invasive shoulder surgery, the care/technical expertise you will receive is cutting edge and based on the best available research for various shoulder ailments (e.g. rotator cuff tears, labral tears and instability). In fact, I am always actively looking for new ways to improve my surgical/nonsurgical treatment methods so you can regain your active lifestyle. Lastly, empathy is a term not often associated with surgeons. This is quite unfortunate, because we are in the ideal position to support patients as they recover from difficult procedures. In my practice, your questions will be heard and answered promptly. By working together, focused on your goals, we can optimize the patient experience and maximize your health and well being.

Patient Comments (35)
in Tacoma, WA |
I found Dr.Koo to be quite terse. I had rotator cuff surgery with him last year and although the damage was extensive he was able to repair most of the damage. After the surgery I never saw Dr.Koo again, only his PA and although she was wonderful it seemed to me that Dr.Koo took no interest in my 9 month recovery. I had to make a special appointment to see him and when I tried ro discuss the pain and limited movement with my shoulder he flippantly said "Ive done all I can for you" and left .
Sammamish, WA |
Everyone who works with Dr. Koo and Claudia says amazing things about them, and now that they’ve done my surgery I understand why. Not only was the surgery more successful than my prior surgeries, but I was better prepared for it, I felt less pain, and I’m recovering faster. I often get asked advice as to how to prepare for shoulder surgery. At this point my answer would simply be to go to Dr. Koo and Claudia, and to do everything they say.
in Redmond, WA |
Dr. Koo and his (PA) Claudia are exceptional medical providers. I have been associated with Pro Orthro since the beginning of time. I have never had a bad experience with any of the doctors, would highly recommend them to anyone.
in East Wenatchee, WA |
The quality of care and the whole overall experience with Dr Koo and his staff was so wonderful. Every step from my beginning office visit to my post op apt went flawless.
in Monroe, WA |
I finally made the decision to have my shoulder repaired after postponing surgery for many years. The pain had become unbearable and was a 'quality of life' issue. After meeting with Dr. Koo, MD and his assistant, Claudia Kaloty, PAC, I knew I had found the right team. From day 1 I felt much better and now, 6 months after surgery, I feel like a million dollars, pain free with a great range of motion. This surgery was the best decision I have ever made.
Seattle, WA |
I had an excellent experience with Dr. Koo. Over the course of about two and a half years, I was dealing with a painful shoulder injury. I had seen quite a few medical practitioners in the past for this injury, including several other shoulder surgeons in the Seattle area, with no resolution or even a clear indication of what the problem was. Dr. Koo was able to both diagnose the issue with my shoulder and resolve it completely via surgery. I'm very thankful for his efforts.
Seattle, WA |
From my initial visit, through my surgery and follow up visits Dr Koo and his staff have done an excellent job evaluating my condition and explaining what they would do and what I needed to do and expect. My appointments have always run on time and been a very positive experience. My shoulder feels a lot better now than it did before my surgery, and I'm not anticipating any problems getting back to the athletic activities that I enjoy.
Issaquah, WA |
Hi Dr. Koo, I had appointment with you on 04/11/2017 at 2:45 PM. This appointment was rescheduled as you were not available lasy Friday. I reached 30 minutes before the appointment. Checked in. Since I was not called till 2:50 PM, went to receptionist and asked about it, This person told me doctor is running 20 minutes late. Since I had another appointment at 3:30 had to leave by cancelling the appointment. It would ave been good if they called me in advance and told regarding the delay.
Redmond, WA |
Dr. Koo was able to see me quickly, took time to explain all options (including not having surgery). He met me prior to surgery to explain everything, as did his PA. Surgery went smoothly and now a year later (6 months of PT) my shoulder is 100% better!
Sammamish, WA |
Highly professional and skilled, excellent surgeon who listens well to patients
in Enumclaw, WA |
I had torn my rotator cuff and my bicep tendon was shredded. I lived with it for about a year and finally decided to get surgery. Dr. Samuel Koo was recommended by my physical therapist. It was the best decision I ever made. He made it very clear to me what needed to be done. What convinced me was when he told me that Brett Favre had the same surgery done and the following year was his best year as a Pro Quarterback. Bottom line, a torn tendon will NOT heal on it's own. Dr. Koo is brilliant!
in Kirkland, WA |
I had a torn rotator cuff and was told it would be a 3 1/2 hour surgery by a prominent surgeon. I turned to Dr. Koo as a second opinion. He did a wonderful job, including an undiagnosed torn bicep muscle in an hour and a half. Eleven months later all is well. I highly recommend this gentleman and his assistant Claudia Kotaly to anyone in the Kirkland or immediate area if shoulder work is needed.
in Renton, WA |
This is an excellent Dr. He takes the time to do things in a way that ensures an optimum outcome. Having both shoulders repaired for calcification of followed by repair of rotator cuff, and second procedure to remove crazy invasive scar tissue, I can assure any reader of this testimonial they will be in good hands with Dr. Koo, and I can confidently recommend him to any person with a similar problem.
Seattle, WA |
Best experience!! I saw another physician in the same office and left the visit feeling unsure, I did research and scheduled to see Dr. Koo instead. He repaired my shoulder and I am now back to normal. His entire staff was easy to work with and I have nothing but good things to say.
Seattle, WA |
From Yakima, happy with his team.
Seattle, WA |
Delightful to work with his PA Kalotay in all post op visits over the year.
in Seattle, WA |
The pre-operation experience and actual procedure were both professional and supportive with the end result being excellent.
in Bothell, WA |
No discomfort or pain after surgery for an extensive amount. Prefer Koo over past shoulder surgeons used.
in Poulsbo, WA |
Dr. Koo and his partners are very professional, informative, friendly. I am very pleased with how my surgery and recovery went. I highly recommend Dr. Koo and his staff. Thank you so much.
in Redmond WA |
I would, and have, recommended Dr. Koo to others because of his expertise. I have great confidence in both him and his PA, Claudia. Dr. Koo's expertise about my shoulder issues inspired my confidence in him. Working with Claudia all these months as she answered questions for me and offered advice and encouragement also made me feel well taken care of.
in Enumclaw, WA |
He did an excellent job repairing my rotator cuff. He got me back doing all of the activities I love. His staff and facilities are top notch. He communicated very well, which was important to me as I want to participate in my medical care.
Seattle, WA |
Dr Koo inspires confidence in addressing shoulder problems. He replaced my right shoulder a year ago and I have had an effortless recovery, regaining all of my capabilities. I have recommended the Pro Ortho group to many people who inquired about my experiences with the surgery. Dr. Koo's PA, Claudia, has also provided major support during the course of the rehab period.
in Bellevue, WA |
I was diagnosed with a severe rotator cuff tear. Dr Koo thoroughly explained non surgical and surgical options. Surgery and recovery went well and am now 9 months post surgery and back to my regular routine. I have full range of motion and pretty much back to full strength but still need to be careful for another 3 months.
in Seattle, WA |
It was awesome. He really listened to me and choose the surgery that we both felt was best for me. Theat was reverse shoulder replacement. The surgery was so successful, I have almost full motion and it's only been 3 months. Claudia rocks too!!!
in Renton, WA |
After several years of physical therapy for shoulder pain I saw Dr. Koo and found out that I had serious shoulder injuries that needed surgery. Dr. Koo was able to perform surgery within a few weeks to start my road to a healthy shoulder. The surgery left very little scaring in the 3 points that were used to access the shoulder internals - to my pleasant surprise. Follow up office visits were easy. Post surgery physical therapy seemed unending but I recovered pain free motion and strength.
Port Ludlow, WA |
Dr. Koo performed a rotator cuff repair with excellent result.
in Maple Valley, WA |
Claudia has been excellent before, during and after my surgery. I would highly recommend Dr Koo and Claudia.
Seattle, WA |
I was pleased at how well Dr. Koo and His assistant Claudia listened to my concerns. The follow up care was very thorough and I am pleased with the time they took with me.
Seattle, WA |
Highly recommend Dr. Koo to anyone.
in Bothell, Wa |
Dr. Koo was honest and explained my procedure so that I felt prepared for surgery and recovery.
in Seattle, WA |
Dr. Koo was very knowledgeable and compassionate in his patient care. He communicated very well and was a good listener; he made sure all of my questions were answered to my satisfaction. Dr. Koo used good verbal skills and anatomy diagrams to explain my condition. I would rate him 5-stars (highest) and would highly recommend him to all future patients. My experience was excellent.
in Redmond, WA |
I think the deliberateness and gradual approach to therapy and recovery by Dr. Koo and PAC Kalotay were directly responsible for my full recovery and full range of motion today. I would recommend Doctor Koo and his team without reservation to anyone needing rotator cuff surgery and rehabilitation.
in Kirkland, WA |
Results have been more than expected.
Seattle, WA |
Dr. Koo takes the time to listen to your concerns. He is very thorough and takes your issues and concerns seriously.
in Woodinville, WA |
