My GI doc quit medicine altogether

I can't say I'm disappointed. I wasn't impressed with him. But now I have to find another one.
I like asking my Internist who to go to, because I trust his judgement, but sometimes I think he just calls the group and asks who needs more patients...........which isn't always the best choice.
How did you find a good IBS doc?
I imagine alot of GI docs don't want alot of IBS patients, since we're sort of hard to figure out!
Thanks.
