I picked this practice mainly due to the large number of their doctors that were ranked in the Washingtonian magazine and I have not regretted that decision. I was able to make an appt with my doctor of choice and had a good choice of appt times. If you are pregnant you can go for an open house where you will surely be impressed by all the additional details they will share with you. The practice is very solid with two locations in Herndon and in Fairfax. All records are stored on the computer so you can easily go between the two locations where all the drs spend time back and forth. There are nurses always manning the phones to answer your questions even on the weekend (ltd hours on Sat and Sun). I've tried two other practices for my kids and this is surely the BEST!
