I wouldn't have anyone else but Dr. Martz work on me. He replaced both knees. ulnar nerve transpositions on both elbows. my lower back, (3, 4 and 5), and my right shoulder rotator cuff. .He is very good at listening to a patient and will answer questions. His staff was very up to date on any papers needed for work or insurance. His "bedside" manners were the best. I cannot believe any surgeon in Columbus could be better.
