This doctor is one of the best I have ever met. He treats each patient individually and fully. He is passionate about making sure that his patients improve. If they don't, he will keep digging to get to the root of someone's problem. He truly cares about his patients. His staff at the Knoxville office that I go to are some of the nicest people ever! Most doctor's offices the staff always seem put out when you ask them for something. Dr. P's staff is always willing to help you!
