Awesome practice!! The staff was professional and courteous, but what stood out the most was Dr. Harrington! We had been to 3 other dermatology practices, and no one was able/willing to do the necessary procedure to help my son. Dr. Harrington went above and beyond what was ever expected to ensure my son's procedure was completed before he returned to college and made himself available for any questions and concerns.

Best dermatology practice in state of Maryland. I could tell my husband, Ralph, was nervous but Dr. Harrington was so kind and reassuring. The staff were very nice and kind. Special thanks to Michael. Thank you so much for taking such good care of him during his surgery.
