Meet the Team

We are extremely proud of our long-established dental team.

We figure that working together as a convivial, professional team for ten to 25 years is quite an accomplishment, particularly in this day and age. With over 30 years of combined experience,  the professional staff of Encore Family Dentistry shares the pleasure of really getting to know all of our dental patients  under our care. Some of our professional staff have had the pleasure to see some of our younger patients grow into adults and become our patients on their own. Whether you’re an old friend or new in town, you can be sure that when you come to our office you’ll be warmly welcomed by our staff!
