DR MARK DAVIS is an awesome doctor. After going to the "best" doctors at Georgetown University several times without resolution to my medical issue, HE was able to give me a proper diagnosis and treatment. I dealt w/this issue for more than a year and 1 visit to Dr. Davis gave me all the answers and the cure that I needed. An angel in disguise is what I call him. He is truly blessed. The other medical staff are all very professional yet personable. Everyone makes you feel right at home! What a great place to go. I would recommend it to any and everyone!
