I've been going to CWC's Alexandria office for years and have had a great experience through many "issues" that have popped up. I've also been to a few of their other office locations (Falls Church, Fairfax) as needed. Dr Hou is my primary OB, and I can't rate him high enough. Now that I'm pregnant and seeing all of the different OB's in the practice, I would reinforce that my preference is for Dr. Hou, but they all seem capable.
