Consultation review - Great Doctor. Ashburn, VA

I never went through with the Invisalign with this dentist only bc he was too far out for me to travel and the traffic is just miserable. I did, however, take myself and my son for a consultation and he and his staff were really fantastic. He's very personable and they really gear this office towards kids, which helped a lot since my son has way too much energy for a typical office setting. Spent a lot of time w us as well and his office includes a whitening, which you definitely need after these gross trays have discolored your teeth. My current ortho does not include whitening. Drat! Anyway, I wish he was located nearer to us. Great experience!!
