Meet the Doctor

Michael Billings, DDS


I love being a dentist! Dentistry provides me the unique opportunity to interact with, and provide care for people, in a way that can make dramatic improvements in their lives.  I feel fortunate to be able to improve our patients overall health and self-esteem. With modern technology we can provide these services more comfortably than ever before.

As a 2009 graduate of the University of Maryland I received training in all aspects of general dentistry to provide quality care for both adult and pediatric patients. To provide better care for my patients I have received advanced training at the Pankey Institute, Garg Implant training institute, and as a member of numerous study clubs including the Seattle study club and Chesapeake dental implant study club. As an active member of national and state dental organizations such as the American Dental Association, Maryland State Dental Association, and the Academy of General Dentistry I hope to continue my education and deliver the best possible dentistry.

Having been born and raised in Maryland, I have developed a passion for all that Maryland and the Chesapeake Bay has to offer.  On the weekends I greatly enjoy spending time on the water with my wife Laura and my two girls Abby and Kate.
