I was trained in the use of the Yag laser for perio scaling and desensitization, and also ultrasound therapy for TMJD. I have accumulated over 400 hrs of continuing ed. I believe that the smile has to be healthy and happy before it can be beautiful. Each person achieves this in his or her own way and time.

A dental visit should be as pleasant as possible and my goal is to get everyone to look forward to the hygiene appointment.
