Testimonials

Dr. Petraco and his staff are wonderful. I had two full knee replacements done, and what I like about Dr. Petraco is he tells you the truth, he does not sugar coat anything. That is what I like about him. He knows exactly what he is doing. Plus his staff is great, after surgery had questions left messages, they got right back to me. I trusted him with two full knee replacements, and 5 years later my knees are fantastic. Dr. Petraco is the best at what he does.

Short wait time. Professional staff, on-site x-ray and resolution to my hip pain. Dr. Petraco was friendly, thorough and explained the source of my pain. He was able to provide relief and assurance that I would feel better within days and asked me to call if I needed more assistance. I highly recommend the doctor and this practice.
