Dr. Karnasiewicz performed back surgery on me almost 4 years ago. He helped choose the right procedure and I couldn't be happier. He has great bedside manners and I would definitely recommend him .

I was 15 years old with a very high risk sarcoma in my spine. Dr Karnasiewicz operated on me and played a big role in saving my life. I am here 30 years later. Very skilled and compassionate surgeon!
