Dr Theo has been my primary psychiatrist and therapist for a little over a year now. She is by far the best child psychiatrist in the McLean area. she is not only experienced, incredibly intelligent, kind and open, but she is also the only doc I have ever been to that does two special things for her patients. 1. Dr Theo NEVER prescribes medicine unless she is 100% sure a patient needs it, and only when she knows them and their history well. 2. She always prescribes the most cost effective meds.
