Mat Pendergrast has been our family Dentist for a generation. Last month, he took me in to fix a cracked tooth at 7AM on a national holiday when he was supposed to be closed. He is tha kind of guy. His staff has almost no turnover. That says something to me. He has installed flat screen TVs in that swinging light and mirror apparatus to entertain the kids with Disney movies. The office is easy to find half way between Damascus and Germantown.
