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! (5 star Review from Evenlyn B. in Stamford)
