As far as conventional practitioners go, I recommend
capital digestive care. I think they accept most insurances.
Try your darndest to get D-r.Kriesburg if you can. He's young, knowledgeable and up to date on the medical literature. He's also pretty well versed on unconventional therapies like LDN and fecal transplantations and won't hesitate to make those suggestions to you.
For integrative practitioners, I recommend Robynne Chutkan @
The Digestive Center for Women. You'll have to shell out cash, but I think she's one of the best GIs in the world (along w/ Dr.Thomas Borody). She has a pretty darn good understanding of the role that hormones play in gastrointestinal disorders in women.
