There are guidelines online elsewhere, you don't necessarily need an endocrinologist with experience treating trans patients, the doctor just needs to understand what the areas of concern may be. A 5 mile radius is a pretty small area, though...I know some people in my state drive more than 50 miles to the endo I see, and pretty much everyone I've talked to in this state goes to him. But, all he really does is make sure I'm staying healthy on my current regimen, that my hormone levels are adequate, and of course he writes the prescriptions. It is nice to know that he has experience with dozens of other patients, if only because he knows how to fill out the forms with my insurance to not get HRT-related treatment kicked off my plan...
Are there any trans resources in your area or reasonably close by? My therapist is about the only person I found completely on my own, the other people she put me in contact with helped point me in the right direction on the more "practical" things.
