Dr. Erfan is both excellent and generous. He participates in the Md. Child Care Health program that provides health care to low-income families (and pays him far less than his usual rates). I have brought three children to him ages 6, 15 and 16. All three love him. He is patient, gentle and thorough. Really--the 6 year old *wants* to go to the dentist! We drive from College Park all the way to Gaithersburg because he is so good.
