An amazingly talented surgeon, Dr. Kowalsky should be your go to for any shoulder, knee or other related needs. He operated on my shoulder and bicep and they have returned to near full function with very little pain or difficulty in healing, with, of course, additional related physical therapy. I would send anyone to him without reservation. Five stars. Phenomenal.

He is a very good Doctor. He fixed a torn Tendon in my elbow as well as got rid of a bone spur and burcitis at the same time. He explained everything very well. He is friendly and a pleasure to talk to.

I highly recommend Dr. Kowalsky as a surgeon. He is very knowledgeable and spends plenty of time during office visits to answer questions & explain the surgery. I had a 100% success rate for rotator cuff surgery. Dr. Kowalsky overlooked post-surgery exercises and followed my PT for rehab. The office staff is efficient, friendly and well-run. I highly recommend ONS and Dr. Kowalsky!
