My family has gone to the Annandale Family Medicine group for about ten years. No medical office is perfect (hence the 4 stars, rather than 5, which says it means "perfect") but AFMed is the best primary care doctor's office I have gone to.
The other reviewer seems to have gone at a difficult time for the office, back in 2003. I have explained (and accidentally duplicated) what happened then, and why I don't think it suggests there will be any problems in the future.
We love Annandale Family Medicine. They see us promptly, they respond well, and they provide good service.
