I loved my OB GYN - Dr. Scott ###-###-####). He's a one-man practice and really spends all the time you need with you. really unusual! But it can mean long wait times - so try to book early morning or late afternoon if you decide to go with him.
We also really like Sleepy Hollow Pediatrics - we've been happy with all of the pediatricians there and I've heard good thing about Northern Virginia Pediatrics.
