Dr. Gruntz is a great Dentist and a SUPER guy. Very personable and fun to talk to . Nice small, pleasant, intimate office that is very convenient in the Crystal City area. You can walk under cover to the Metro or free parking is easily available.
I have used Dr. Gruntz for longer than I have ever used any one Dentist. I plan to use him for all my general denistry work as long as I'm in the DC area.
I highly recommend him.
