My DD sees Dr. Skordalakis, who has offices in Leesburg and Vienna and apparently has quite an extensive special needs practice. The Vienna location is new, so he only sees patients there on Fridays, but it also means he's still taking new patients. I know two other families of kids with special needs, one who has extreme anxiety, and they see him as well. The kids all love him and he does a FANTASTIC job! At our first appointment DD wasn't even 2 years old yet and she did just fine with him.
