What advice do you have on finding a doctor?

After a long series of events surrounding my health, I have zero faith in any of the doctors I’ve been to in this town (Houston, TX, US). The only way I’ve generally found doctors before is through the recommendations of friends and other doctors. Well, since I don’t trust the doctors I’ve been to here, I don’t trust their friends either, and my friends have been to basically the same people I’ve been to.

I need an internist right now, but I’ll probably need a gyno, too eventually.

Suggestions?

Also: My insurance is pretty flexible. I can see whomever I want, it makes no difference to them.
