Review by Geri ***** August 27, 2026

5/5
Dr. Chamernik is the most caring orthopedic surgeon that I've ever met. I had a reverse total shoulder replacement surgery that went very well. He actually sat down with my husband after my surgery. Best bedside manners. Thanks to all the staff at The Center for Sports Orthopaedics and the PT staff for all that you are doing for me to regain strength and range of motion! You are all amazing!
