Me and my entire family use Dr Penner's office and they're the best especially if you're anxious about dentistry at all. I don't think he's any more expensive than other dentists, and he bills my insurance first, and then bills me. I have seen some dentists that demanded that payment be made up front and insurance pays me... He also doesn't charge for nitrous oxide which many dentists do. His staff is supportive and cheerful and have turned me from being a sworn dentist-phobe into someone who visits now every 4 months for a cleaning.
