The efficiency and friendliness of the staff go a long way in easing the somewhat dreaded dental visit.
Actually, i never dread it. I've been a patient here more years than I can remember, and have been more than satisfied with the level of care I've received. I have referred family and friends and all have had a positive experience.

Best dentist ever! Knowledgeable, thorough, great staff, good communication and kind. I’ve been a patient since the mid-1980s when I walked in a dental chicken from bad experiences with a pediatric dentist and walked out knowing Dr. Darrell Otsu sees every patient as a person and not just another mouth. He advises on options of treatment, insurance/finance strategies and has always answered the phone personally in dental emergencies over the years. His staff is amazing and I enjoy interacting with them. Highly recommended!
