I chose Dr. Nathan from a list of specilaists given to me fifteen years ago by my general dentist. It was one of the best decisions I have ever made. I have complex tooth and gum problems, and Dr. Nathan has helped me every step of the way. The surgeries and deep cleanings and scalings I desperately needed were accomplished with a minimum of pain. Dr. Nathan and his fabulous assistant Elaine even helped me stop smoking, and I haven't had a cigarette in over 13 years. Dr. Nathan and his staff meet the highest standard both for professional care and patient service. I highly recommend this office to those seeking the services of a periodontist. It's the best.
