There's probably a transgender resource center in your state, call them up, and they can point you towards trans friendly therapists. The way I found mine was by calling and asking the therapists myself. That method worked out pretty well, if you feel courageous enough to do so. Just keep in mind, nobody will know exactly who you are over the phone, you don't even have to give your name, until it comes to the appointment scheduling part. As Laura said, diligence is going to be a key factor. Best of luck!
