What Our Patients Are Saying
Meet The Doctor
Dr. Gregory Nielsen
Dr. Gregory Nielsen offers extensive experience, genuine compassion, and a strong dedication to patient-centered care. Originally from Northern Virginia, he spent many summers visiting family in Massachusetts—experiences that fostered a lasting connection to the New England community he’s proud to now call home.
Dr. Nielsen earned his Bachelor’s degree in Chemistry with a minor in Spanish from the University of Virginia, and later graduated summa cum laude from Boston University School of Dental Medicine. While at BU, he was inducted into Omicron Kappa Upsilon, the national dental honor society, in recognition of his academic excellence.
He completed a two-year General Practice Residency at the University of Virginia Hospital, where he received advanced clinical training in oral surgery, sleep dentistry, endodontics, orthodontics, and periodontics. A particularly meaningful aspect of his residency was working with the head and neck cancer team, helping patients prepare for radiation therapy—an experience that deepened his appreciation for the vital link between dental and overall health.
After residency, Dr. Nielsen returned to the Boston area and has since been providing comprehensive care in private practice. He is known for his thoughtful, individualized approach to dentistry, always taking the time to understand each patient’s unique needs and goals.
Outside the office, Dr. Nielsen lives in Boston and enjoys playing golf, basketball, and cycling. He’s also an avid reader of science fiction—so don’t hesitate to share your favorite book recommendations! Though he remains a loyal fan of Virginia sports, he admits that Boston’s teams are starting to win him over.
