I live in Sellersville but go to the OAA’s Allentown office. I pass a lot of other orthopaedic offices along the way, but I will gladly make the trip for this group any day of the week. One or two days between making the original call and getting an appointment. Total knee replacement was a breeze. I've seen 3 different doctors at OAA and every single one of them treated me like a patient and not an account number. Great group of doctors. Thank you!
