Roger R. Lacoste, DMD


Doctor of Dental Medicine, Specializing in Endodontics

Southcoast Endodontics got its start in 1976 with the opening of a practice by our founder, Dr. Roger R. Lacoste.  Dr. Lacoste received a BA from College of the Holy Cross and a DMD from the University of Pennsylvania. He went on to receive a post-graduate certificate in Endodontics from Boston University. Active in local, state and national dental associations over the course of his career, he was always at the forefront of advancement of his profession.  A pioneer of new technologies, Dr. Lacoste was one of the first in the area  to incorporate the use of digital radiography, operating microscopes, and microsurgical techniques in Endodontics. He served as a consultant to the development of Endodontic practice management software, and has been a lifelong learner.

Our practice has grown under his leadership and now includes four locations serving many towns in Southern New England. Dr. Lacoste’s strong work ethic, and passion for delivering the highest quality Endodontic care for patients inspires us every day. His example instills the values and integrity that are at the core of our mission at Southcoast Endodontics, that is, to work hard to provide technologically advanced, compassionate and effective dental care. Although retired from practice, he frequently visits the office to check on operations and offer his expertise.
