Excellent dentist and professional staff! I have been a patient of Dr. Raff's for more than a decade. This is a dentist who truly cares about the service he provides! I know I can count on Dr. Raff 24 x 7 service when and if I am in pain. On once occasion I had to have a root canal performed on a Saturday afternoon; I was surprised that the whole procedure was completed quickly and effectively with no pain at all! Dr. Raff is current with dentistry, is open to innovation where and when it counts with an eye and focus on delivery of quality service to all his customers! I am always impressed with his extensive level of knowledge in this broad field. I am very lucky to have the "best" dentist in San Francisco!
