I'm always satisfied when I have an appointment. This one was sort of an emergency and everything was handled well.

Kathy did a very thorough job cleaning my teeth and pointed out two issues about my teeth and gums that I should know about. She also explained how to better take care of one area in the gum line that needed more attention.

This is a very positive office from the moment you walk in. The front desk receptionist is always friendly and attentive. The dental experience is second to none. I have routine cleanings and recently needed a cap. All was managed to my time schedule, efficiently, professionally and curiously. I enjoy, that's right, enjoy going to Keystone Dental.
