http://www.covd.org/ - start here. The first Doctor we saw tried to "frighten us" into very expensive treatment. (I posted about it here sometime in January, I think.) Anyway, His testing was subjective and seemed random and his personality was very "hyper"- DD did not mesh well with his energy level. We later googled him and found that he had failed the licensure in two states.

The doctor she sees now is a well known DO in the area and I have yet to find negative information on her. Her testing is objective (computer driven). She is calm and confident and when dd "tested her", she called her on it with firm controled certainty. My dd didn't like it then, but she loves it now!!!

I would say ask the doctor for references, check the internet, read the "fine print"...check your mom gut!!!

Hope this helps!
