It is one of the most prominent U.S. military medical centers in the Washington, D.C. metropolitan area and the United States, having served numerous U.S. presidents since the 20th century.

Back in 1993, Dr. Massey IV graduated with his medical degree from the Wayne State University School of Medicine. He then went on to perform his internship at the same educational venue in 1997, and his residency in internal medicine at Howard University in 2000.
