  • “Thirteen years of service for myself and my children. I trust that I will have excellent care and as painless as possible! Absolutely awesome dentists, and office team is exceptional! These folks are like family!”

    - Margie C

  • “Dr. Powell and Dr. Tiller are both WONDERFUL dentists. When I picked my children up from school, they were so excited to go to the dentist, the school receptionist commented on how she NEVER sees that when kids are going to the dentist. I don’t think I have ever felt more comfortable being at the dentist.”

    - Marie T

  • “I have been a patient at Dr. Powell and Tiller’s office for 10 years now. I see Dr Tiller specifically, but they are both really excellent doctors. When I have needed referrals (TMJ or root canal), Dr. Tiller always sends me to the best. In emergency situations, it is always easy to get an appointment promptly.”
