Meet the Doctors

Dentist in North Billerica, MA

All our professionals at New Concepts Dental Group maintain the highest levels of accreditation and pursue ongoing education to stay abreast of the latest trends in dentistry.

We chose the name "New Concepts" dental group in 1984 to convey our commitment to offer the latest in technological advances in the field of dentistry. But, just because something is "new" does not necessarily mean that it is of benefit to the patient. Sometimes new products, a new techniques or a new piece of equipment just duplicates something already in use at a much lower cost to the patient. We only incorporate a "New Concept" when it provides a significantly improved benefit to our patients.

Over the years we have found the best "Concept" is the use of mature clinical judgment in the treatment of our patients.

Our facility is located in North Billerica just off Boston Road (Rt 3A) about 1.8 miles north of Billerica center. We are on the right side going north. Our address is 330 Boston Road, North Billerica, MA 01862. Our office is located in a free standing 3200 square foot professional building. We occupy the entire building. Our phone number is 978 663-7638.

Our facility was designed and built by us in 1987. There is plenty of parking and we are wheel chair accessible.
