Meet Our Dentists Greenbelt

Four Generations of Dental History in Greenbelt, Maryland

The town of Greenbelt was designated a National Historic Landmark in 1997. It is one of three planned communities that were created during the Great Depression as part of the New Deal to house low-income families. Championed by Eleanor Roosevelt, the residences constructed in a park-like setting adjacent to a town center are remarkably preserved today. The Federal Government implemented a health insurance plan with salaried physicians and hired two physicians and one dentist to serve its population. The town dentist was the only private practitioner, and that individual was Dr. James W. McCarl, who graduated from dental school in 1924. Appointed to the position of town dentist in 1938, he practiced dentistry at the original location, 30 Ridge Road until 1955 when he purchased 28A and 28B Ridge Road.

He was joined by his son Dr. J. Taylor McCarl in 1955, and the two practiced dentistry in one half of the 28 Ridge Road building. In 1956, Dr. Clayton McCarl Sr. joined his father and brother, and they remodeled 28 Ridge Road to make one large dental building. They practiced together for 11 years, until Dr. James W. McCarl’s death in 1967. Dr. Clayton McCarl Sr. and Dr. J. Taylor McCarl practiced for a total of 32 years together, with Dr. J. Taylor McCarl retiring in 1988 and Dr. Clayton McCarl Sr. retiring in 1998.

Today, Dr. Dianna Lee, Dr. Richard Duarte, and Dr. Tommy Lam, as well as Dr. Clayton's sons, Dr. Clayton McCarl, Jr. and Dr. Jay McCarl, are those that lead the charge at our office.

What started as a part-time, high school job as a dental assistant for Dianna Lee has grown to a full partnership in our dental office. While working at our office, Dr. Dianna Lee went on to award-winning degrees at the University of Maryland College Park and the University of Maryland School of Dentistry. Her experience spans decades and includes Invisalign certification and cone beam 3D imaging. Dr. Dianna Lee is also able to perform guided dental implant surgeries.

Dr. Richard Duarte’s experience with dentistry started at a young age because of the extensive orthodontic treatment he required. However, his passion for the field grew and led to him working as an assistant in high school before graduating from the University of Maryland, College Park, before earning his dental degree from the University of Maryland School of Dentistry. His breadth of knowledge and experience includes Invisalign, dental implants, smile makeovers, and more.
