trans | choosing a doctor

Hey, everybody - does anybody have any suggestions about choosing a doctor? I've had estradiol and spiro prescriptions for years, but I'm leaving one medical system and need those prescriptions renewed in another. I'm not trying to change any dosages or anything so it should be really simple. I'm starting from scratch - I don't even have a general practitioner yet.

Should I look for an endocrinologist or a gynecologist? If so, how do I find one who has dealt with TG prescriptions before? (I think there are a lot of endos who don't do much with sex hormones at all.) Or should I just ask my GP? If so, how do I choose one who will cooperate? Choose one off the list at random?

I have emotional feeling that it will go better with a woman doctor, but I hate to discriminate and that may be inaccurate anyway... there are plenty of women out there who polish their Gender Police badges daily.

Just wondering how the rest of you selected doctors.
