Dr. Hefflefinger and his hygienist Jan are both wonderful, I've been going to them for 20 years, and they've helped me through a lot of dental issues. Conveniently located off of the Beltway, they are easy to get to and I've never waited more than 5 minutes to get in for my appointment - but they do have the best up-to-date magazine selection in their waiting room! The office is in the first floor of a home that is very comfortable...and comforting! Dr. Hefflefinger has a dry humor, and is a bit "old school" but in the best most experienced way - he doesn't try to "up-sell" you like a lot of new younger dentists do these days. You can tell that a lot of his patients have been going to him for years, a good sign of a good dentist! read more
