Well, I'm not sure if it's good news but I'm on a waiting list for vocal therapy at a local university's Speech and Language clinic. No idea how long the wait list is, but hoping worst case scenario something will open up at the end of the semester when the students go home for summer.
In the meantime I'll keep searching for a speech pathologist somewhere nearby that has transgender experience, but so far that's been harder to locate than I thought it would be.
