Our Doctors

Our doctors are committed to providing exceptional oral care that is appropriate and relevant to each patient’s personal needs and preferences. Respectful of patient wishes, we are committed to providing the best care — from routine cleanings and basic dental care  to cosmetic services  including Invisalign®, esthetic restorations and CEREC® (crown in a day). With advanced technology and an in-office milling lab, we are able to offer solutions that save you time, minimize discomfort and provide exceptional results.

Our office specializes in Smile Makeovers – a transformative process utilizing cosmetic and restorative dentistry to improve both the health and appearance of your smile. Our “Before and After” technology allows patients to see the transformation before treatment has even begun!

Named one of Boston Magazine’s Top Dentists for 2018, our patients value our collaborative approach and put their trust in us. We seek to educate, inform and advise our patients to help you make the appropriate choices for your own present and future dental health.

Graduates of leading local dental institutions, our doctors continue to expand their knowledge and expertise through participation in continuing education experiences and dental studies exploring advancements in treatments.
