Thank You!

5 5 1
I wanted to anyone that needs a total knee replacement or other procedures that Dr. Smith performs, that from the first meeting, I could tell that I would be pleased to have him for my surgeon. First, he is down to earth, personable, made me feel at ease right away, and I thought the most important about Dr. Smith is, he is very passionate about his gift as an Orthopedic Surgeon. I think that is important. He stays up to date in his profession. I am very pleased with my new knee. Thank you!

Love This Guy

This was my third ortho I visited for my knee. The other 2 Prima Donna wanted instant surgery. Dr. Untch believes it should be a last resort. And it works! Listens to your fears and works with you. Love this guy. Wish he did backs too!

Exceptional Doctor

He very successfully performed hand surgery on my left hand a few years ago, and I’m doing great now. It took a while, to heal and that was a little scary, hand surgery is pretty serious. He is an exceptional Dr. I have to thank my pcp for the great referral.
