Hopefully others can chime in with specific information, but I can give you a general approach.
I also had trouble with my previous endo and discussed my methods for finding a new endo.
There are a number of sites that will let you look up endochronologists in your area. You can then look through the ratings sites to see what people say about the doctors (I discuss this in my methods discussion above). When I looked at the comments about my old doctor, I found comments that echoed exactly the problems I had. When I read the comments about my new endo, I found key information about her, she was a good listener, she was sharp and she really had patient centered care. On the other hand, she often ran very late, as much as 2-3 hours because she often spent extra time with patients when they needed help. Certainly a negative for some, but I consider that wonderful, I just schedule my appointments for first thing in the morning.
