Conditions & Treatments Include:
Dr. Kowalski besides being very caring, professional and friendly did an amazing job putting our son’s broken humerus bone back together. The follow-up xrays revealed an amazing progress and almost seamless recovery. We are very grateful to Dr. Kowalski and his staff for taking such great care of our young athlete and enabling him to get back to skiing, training and competing in record time! (5 Star Review on Healthgrades from a patient in Darien, CT)
Dr. Kowalsky is the absolute best! Following a serious sport related injury (elbow), I was treated with the utmost professionalism and personal care. He talked me through every step of my recovery, checked in with me, was there when I had questions/worries about being able to return to full activities sports, etc. A year later, I needed emergency surgery (meniscus repair) which he did too. He took such amazing care of me! His level of expertise and personal involvement is unparalleled! (5 Star Review on Healthgrades from Steven D. in Greenwich, CT)
Dr. Kowalsky – I had my left meniscus repaired by you in October 2016 and my right meniscus repaired in April 2017. My desire was to get back into marathon running. I completed my 15th marathon on Sunday, January 7th at Walt Disney World thanks to you and your staff’s expertise and assistance. I can’t tell you how much I appreciate the ability to be back running. Again, thank you. (Dennis N., Greenwich, CT)
So much praise for Dr. K so I hope this will sum up who he is as a physician, surgeon & man. He knew I was pressed for time to get my meniscus repaired so he scheduled me first thing in the morning (also my preference). As I was leaving after recovery, I met him in the parking garage. He came in early to operate on me alone and then went on with the rest of his day! Who does that but a kind, compassionate, considerate human! Also, I came home with pics which he explained later. I’m eternally grateful! (5 star review on Healthgrades from Jessica C. in New York)
I had ACL surgery with Dr. Kowalsky and it went better than I would have hoped! I’m currently 5 months out of surgery and feel great. Thanks to Dr. Kowalsky and team for making me feel comfortable as well as answering all my questions along the way. (5 star review on Healthgrades)
Dr. Kowalsky performed ACL reconstruction on my knee and I couldn’t be more thrilled with the result! He’s an excellent surgeon, but also has superb bedside manager and is willing to spend whatever time is necessary for his patients to feel informed and cared for. He managed my expectations all through the process, from surgery through physical therapy. I’m cleared for skiing again and couldn’t be happier. (5 star review on Healthgrades from Karen in Norwalk, CT)
Dr. Kowalsky repaired my non union clavicle. I had a graft and 2 plates. I now have full range of motion on my shoulder. Dr. Kowalsky is a skilled surgeon and has a great bed side manner. He spends time with you and explains procedures every step of the way. I could not have asked for a better surgeon and doctor. (Five star review on Healthgrades from a patient in Weston, CT)
I had a complete tear in one of my rotator cuff tendons. I had gotten 2 opinions, one locally and the other in NYC. I had heard of very positive results at ONS through a relative and scheduled an appointment with Dr Kowalsky. It was an instant fit, I was ready to make my decision. Dr Kowalsky took time to go over my MRI and my injury in detail and also his surgical procedure to repair it. The recovery process was also explained so I knew what to expect. Great results and great doctor! (Five star review on Healthgrades from Althea in Easton, CT)

Dr. Kowalsky took EXCELLENT care of my 12 year old son who needed shoulder surgery. He is an outstanding doctor from beginning to end. (5 Star review on Healthgrades by patient’s parent from Harrison, NY.)
Thanks to Dr. Kowalsky, my knee surgery was very easy. I had no pain and the recovery time was unexpectedly quick and easy! I did not have to take any painkillers. He really knows what he’s doing! Thank you Dr. Kowalsky! (comment from Health Grades)
I was so pleased with Dr. Kowalsky‘s professionalism. He was very thorough and spoke to me in “real talk” so that I understood what was going on with my shoulder. I also liked the fact that he told me if I had any questions or problems to feel free and call the office. I called him about a medication I was taking and his nurse got right back to me. I highly recommend Dr. Kowalsky. (comment from Health Grades)
I had a serious knee accident with 3 detached quad muscles at the age of 68. Dr. Kowalsky performed a surgical procedure to reattach them all. I’m able to ski and bike again! Recovery takes time but I’m very happy with the results. Thanks so much! (comment from Health Grades)
Thanks to Dr. Kowalsky my surgery went extremely well. I am mystified at how I am recovering faster than I had expected. (Patient Survey)

Dr. Kowalsky is one of the best and most caring physicians you’ll ever find. It is a blessing to be his patient. Thank you! (Patient Survey)

Dr. Kowalsky has really done an excellent job for me. (Patient Survey)
Dr. Kowalsky: It’s almost a year since I met you in Greenwich Hospital. I want to thank you for the wonderful care and kind bedside manner you showed me over the past year. I’m so grateful you were the doctor on call that day. I don’t know how I would have gotten this far without your gentle manner.. I have the utmost respect for you. Sincerely, SM
Dr. Kowalsky was kind and understanding of my desire to “get back” to rowing and dance. He took time to ask questions to understand my commitments to my teams and how important my attendance was at upcoming events. I appreciated his empathy and straight-forward options. He was a nice person too. – (Patient satisfaction survey)
It is always a great experience coming to see one the doctors here. The professionalism and great customer service keeps me coming back even though it is an hour drive for me! (Anonymous online patient satisfaction survey)
