Dr. Matsumoto is very competent as is his staff. My visits have by far been the most relaxing visits I have had to a dentists office. The explanations of what the doctor thought appropriate courses of treatment were thorough but they were long and would be costly. Some of what was said contradicted two other assessments from a dentist and an oral surgeon. Dr. M did say that all dentistry is opinion based on circumstance and the opinion of the dentist and then cost, etc. for the patient. The office is well equipped with modern technology. I felt the opinion offered was valid but not all of the treament, including orthodontics, was absolutely necessary. I was comfortable with the suggestions, especially given that I was told it was his professional opinion that the diagnosis and treatment would serve best but that there were other ways to acheive like results.
