Hello, I'm helping out a friend that needs an endocrinologist in the Phoenix area in Arizona. Does anyone have any trans-friendly locations that they can recommend? And if not in Phoenix, anywhere in the valley?

Bonus if there has been any personal experience. If you don't have any recommendations yourself, can you provide any links that have lists of any good ones?

Thank you so much.

EDIT: I forgot to mention, my friend is 18, if that helps.
