I'm not too sure if this will help or not as I don't know anyone to recommend personally, but I just recently found the
American Association of Clinical Endocrinologist's website. It lists endocrinologists by state and also their interest areas.
This saved me a lot of trouble trying to find one that wasn't mainly well-versed in diabetes and one who at least was familiar enough with PCOS to list it as an interest area!
Much luck!
