I googled "voice feminization in my area" and came up with a company that offers training from an experienced speech pathologist. We've had one lesson and I've already learned a lot. The downside is that they don't take insurance, so I'm paying $90/lesson out of pocket. I justified this to myself that it's not a long-term expense; 6-8 lessons and we'll be done.

@roachmeister I would love to find someone local for in-person lessons, but I haven't been able to find any.
