This was referenced way back in 2012 by Michelle S, but I go to Two Spirit Healthcare even though they're 1:20 drive from home. They specialize in transgender support and treatment. Ann Currier is my therapist, and she's awesome. Their in-house endocrinologist is Joey Knoll, who is handling my HRT meds, and he offered to take on my primary care if my current doctor had a problem with my transition. As it turned out, though my doctor doesn't specialize in TG treatment, he was very cool about it, so I'm comfortable staying with him for everyday medical stuff.
Right now Joey is the only practitioner in the office, so he's a bit overwhelmed with work, but if you can get an appointment with him it's worth it.
Sorry to hear that you're having problems with Barry's office. I know nothing about that practice, so I'm not much help there. It is distressing to hear about an age cutoff, considering I just turned 59.
Good luck,
Stephanie
