My husband and I each only visited D. Rao once. However we were unhappy from the start. Costs and billing were not made clear an although we had the exact same services done, we were charge two different prices. We were told they accepted our insurance when this was not in fact truthful. When we needed to switch to another dentist who did take our insurance we were given the run around about our records. All in all, it seemed very much like a business where they were going to squeeze as much money out of you as possible. I don't trust people like that with my health or the health of my family.
About Hygienist: The hygienist was pleasant and fairly thorough. We were not unhappy with her, but the business practices of the office.
