I guess the first thing you need to ask yourself what are your immediate goals? (Likely the therapist will also ask that).
I was living in a rural area at the time I first saw a therapist. A Generalist was the only choice. Of the only choices there were just 2 that others in my support group had experience with that were "Friendlies". Both needed a lot of educating. One had a lot more, which is who I began seeing.
For me, the goal was help with shedding the ton of Shame, Guilt and other assorted baggage accumulated over a lifetime of not really addressing being trans. I needed help in thinking about myself in more positive ways, unlearning a lot of harmful ways of thinking and acting, and learn better ways to. Sure, a lot had to do with fighting the GD, still, those were the major factors turning my life, my world, into one giant mess. After 2 utter fail transition "experiments" in my youth, a third was not in my future plans at all.
Today, after moving back into the NYC metro area, I have been seeing a for real gender therapist. TBH - a good 60% of stuff is still the same old issues and the rest with the swings of GD and bouncing like a ping-pong ball at times throughout "The Spectrum". She is better in that the better understanding of what many other of her clients go through helps me.
