Our Practice

We are a dental practice devoted to restoring and enhancing the natural beauty of your smile using conservative, state-of-the-art procedures that will result in beautiful, long lasting smiles!  We provide comprehensive treatment planning and use restorative and cosmetic dentistry to achieve your optimal dental health. Should a dental emergency occur, we make every effort to see and care for you as soon as possible.

Not only are we focused on the beauty of your smile, we’re also concerned about your health. A review of your medical history can help us stay informed of your overall health, any new medications, and any illnesses that may impact your dental health.  To protect our patients and ourselves, we strictly maintain sterilization and cross contamination processes using standards recommended by the American Dental Association (ADA), the Occupational Safety and Health Administration (OSHA), and the Center for Disease Control (CDC).

To give you the best possible service and results, we are committed to continual education and learning. We attend dental lectures, meetings, and dental conventions to stay informed of new techniques, the latest products, and the newest equipment that a modern dental office can utilize to provide state-of-the-art dental care. Also, being members of various professional dental associations helps us to stay abreast of the changes and recommendations for our profession.

Our entire team is dedicated to providing you with excellent, personalized care and service to make your visits as comfortable and pleasant as possible.

We thank you for allowing us to take care of your dental needs and look forward to serving you.
