Meet the Staff:

Dr. Edward Mitoma

Dr. Mitoma was born and raised in Oakland, Ca. He graduated high school at the age of 16 and attended Pacific Union College in the NapaValley. He then relocated to Southern California and received his Dental Degree from Loma Linda University. Dr. Mitoma worked at a clinic in Stockton for a number of years, seeing thousands of patients and perfecting his root canal technique. In 1996 he opened up Arroyo Park Family Dental in Livermore. He was one of the first dentists in the Bay Area to offer CEREC crowns that could be milled at chair side and cemented the same day. Dr. Mitoma loves what he does and enjoys staying up-to-date with the latest developments in dental technology. He is an extremely skilled dental practitioner and performs even the most complex procedures. He has a delicate injection technique and often receives compliments from his patients. His confident and gentle manner has allowed him to gain the trust of patients with dental phobias and help them overcome their fears. In fact, many patients who had once needed medication for dental-related anxieties no longer need the medication in order to have their dental work completed. In addition to being an extremely skilled dental practitioner, Dr. Mitoma enjoys the great pleasure of being married to Dr. Nakamura. It's no wonder patients feel like family when they come! The family owned and operated environment takes the impersonal clinic feel out of the experience, and leaves patients at ease and feeling more assured of quality care.

Dr. Mitoma is also a technology enthusiast, and a dedicated sports fan who is always rooting for his favorite teams: The Oakland Raiders, the Oakland Athletics and the Golden State Warriors. His other passion is cars, and he enjoys reading automotive magazines and knows makes and models of all cars ever made. Give him a quiz! He loves a challenge. He is an avid runner who averages 35 miles/week and has completed several marathons. He is a four time finisher of the Ironman, an endurance race that starts with a 2.4-mile swim, then a 112-mile bike ride, finishing with a 26.2-mile run. In addition, Dr. Mitoma demonstrates his musical abilities by playing the piano and singing.

She has a number of patients who have been visiting her since the age of three and still enjoy coming to the dentist. Dr. Nakamura loves oral pathology and diseases of the mouth. She has taken an extensive amount of continuing education in this specialized field. Her injection technique is very gentle and many patients comment on how they didn't even feel it.
