Dr. Williams is qualified to perform root canals and was willing(unlike the endos I've seen) to perform mine without anesthesia and a rubber dam. He performed the root canal with minimal pain and discomfort and I was very pleased with the results. My family has been going to him since he took over the practice of our long-time family dentist when he retired. His office files insurance and checks to see if they cover procedures before you schedule them. His prices are average. He is always pleasant and friendly as is he assistant and hygenist. He recently replaced a receptionist who was at times a bit abrasive.
