I was lucky to find Dr. Farhan Qureshi's office shortly after moving to DC. They are affordable but still manage to offer great quality of care and service which is impossible to find in DC. Most offices are more like spas-with spa prices to boot!
Joan does a great job with my cleanings; I have a small mouth, TMJ, and a host of other complications but she takes it all in stride, and also is the friendliest lady you'll ever meet! This is why I still drive to VA from DC, although there may be more convenient dentists to my home it's worth it to go to Dr. Qureshi.
