After receiving no relief from a major NYC Ortho hospital for a severe case of tennis elbow, I found Dr. Kowalsky. He assured me that even at my age, 66, there was no reason that my tennis days had to be behind me. He performed surgery flawlessly, and I was back on the tennis court in 3 months, playing some of the best tennis I have played in years. I will be eternally grateful to him for not putting me out to pasture and I will continue to recommend him to others. He is kind, caring and an excellent surgeon. Simply the best... read more

This is a follow-up to my 5-star review of Dr. Kowalsky (dated 12/13/18), shortly after I completed P/T and had my last visit with the doctor. I had suffered a very serious shoulder injury while bicycling late May 2018. Dr. Kowalsky performed a complex surgery mid-June to repair my shoulder, which had several tears of the rotator cuff and biceps. I am now back on my bicycle, and doing the somewhat challenging rides that I had been doing prior to my accident, although perhaps a bit more carefully. My shoulder feels great, is ... read more

Dr. Marc Kowalsky is simply the best. I’m 56 yrs old and have multiple sclerosis, as a result my balance is affected & well, I’m always falling and breaking or injuring something! I fell and tore my ACL at the end of 2018. I feel that from the very beginning I’ve received excellent care. Surgery ended up being the best option for me, everything went smoothly and every effort was made to ensure a successful outcome. I had the best post op instructions and follow up care I’ve ever had & ONS Physical Therapy was brilliant. I fe... read more

Not only did he fix my knee physically but he basically turned my way of life around mentally. I would highly recommend him to anyone !!! I cannot speak highly enough about him and his practice!

I saw Dr. Kowalsky for an ACL reconstruction - he was patient and kind and took the time to answer any/all of my questions. Surgery went extremely well and I have full range of motion back in my knee. 

Business response:

Dr Kowalsky and the entire staff at ONS are professional, incredibly knowledgeable about their individual crafts and really cared about getting my knee/quad and leg back to normal so I can resume my daily activities. Dr Kowalsky, despite being very busy took the time to respond to a question via e-mail and I can’t name another Dr who would take the time to do so! Additionally ONS is “one stop shopping” from setting up appts, MRI, surgery and PT all under one roof! Their PT staff is exceptional!

I had a very serious shoulder injury. Dr. Kowalsky clearly and completely explained the extent of the injury and the surgery needed to repair my shoulder. He also accurately predicted the recovery time and effort needed. Dr. Kowalsky always took as much time as was needed to thoroughly answer every one of my questions. I would definitely recommend him to anyone who has experienced a shoulder injury.

Dr. Kowalsky operated on my shoulder for rotator cuff repair a year ago. Excellent result with full range of motion. He is a great surgeon with skills!! Also, very personable and professional. Many people had given me horror stories about their similar surgery and were advising against it. So glad I didn’t listen. I’m about to start playing tennis again which could not have happened without the results I have. Thank you Dr. Kowalsky!
