Doctor Grimmer and staff make going to the dentist as enjoyable as going to the dentist can be. I had an issue with my dental insurance (it had nothing to do with Dr. Grimmer) and the staff was very patient and helpful. It took almost 9 months to resolve the issue with my insurer and Dr. Grimmer's staff was always there to help and to make calls to the verify information to the insurer.
I have recommended them to many of my friends and would recommend them to anybody looking for a good dentist.
By the way, I would avoid UniCare Insurance no matter what dentist you use.
