Dr. Barfield removed a benign tumor from my mandible in 1978. A few days later I was having some problems with the incision. I called his answering service and left a message. He called me back within one hour. He told me he would meet me at his office (this was a Sunday afternoon). Following the surgery I returned to see him once a year. Each time he refused additional payment. These annual appointments went on for 30+ years until his retirement.
He was one of those rare dentists who actually had a personality. During my many visits to see him, he was never in a hurry. He would always listen to my questions and give me straight answers. He was dedicated to his profession and extremely caring of his patients. Dr. Barfield passed away in 2015. A great dentist and an even better man.
