About Your Dentist

“I never forget that there’s a patient attached to that tooth!”

My Mission

To ensure each patient is able to enjoy a beautiful, healthy smile for a lifetime. To educate our patients on the importance of maintaining excellent oral health and how it impacts their overall systemic health and sense of wellbeing.  To help our patients understand the many ways effective preventative dental care can improve their quality of life. More than anything, I want my patients to feel confident that our entire dental team will treat them with the same care, empathy, and attention as we would treat members of our own families.
