Practice Overview

Due to revolutionary studies, we have implemented environmental improvements within our dental office.  We are going green! Our solar powered office uses natural sunlight for power.  We offer BPA-free fillings which are healthy for our patients and the planet.  We are reducing the use of paper and have gone completely digital.  Our digital imaging has erased the need for using toxic X-ray development chemicals and film.
You'll feel right at home in our office while receiving the highest quality care.  Our newest technology includes our computerized anesthesia which comfortably numbs a single tooth.  This allows you to eat, drink, and talk normally immediately upon leaving the office.  Our office provides paperless record keeping, state-of-the-art digital x-rays, iPads for checking in, noise-cancelling headphones, massage chairs, and TV's in every room.  The unparalleled warmth from all of us offers a comfortable and relaxed visit.
