When I’m not practicing dentistry, I enjoy yoga, boating, traveling, swimming, photography, dancing, Zumba, and social events. I'm also a triathlete and have run a full marathon in all 50 states.
I like to treat patients with gentle dental care like they are part of the family. We teach total body health without passing any judgement. I love to treat emergencies to get patients out of pain, and I love cosmetic dentistry to help make patients feel more confident.
