I left my visit with a sense of security. My procedure was explained to me in such a way that I had no questions for Dr. Singer at the completion of the visit. He was very professional and did not rush the visit. I highly recommend him for any of your Orthopedic needs.

Absolutely the best orthopedic practice Dr. Singer and his team at University Orthopedic Center (UOC). Quickly and safely entered building, temperature check, social distancing, less then five minute wait called back for ON-SITE X-RAYS. Barely sat down and nurse took me back to begin exam. Doctor quickly and efficiently reviewed x-rays, completed and determined probable cause, provided treatment, and explained case scenario clearly and efficiently. WILL NEVER GO ANYWHERE ELSE! Dr. Singer and his team are the best!!
