As a former dental hygienist, I was extremely pleased with the treatment provided by Dr. Principi and his entire staff. I had root canals and several crowns seated by Ron and all were high quality with minimal discomfort. He took the time to make sure my bite was correct which is very critical. All of the staff is extremely friendly and helpful. Unfortunately, we've now moved out of Ohio--we miss Dr Principi! I highly recommend this practice for the whole family.
