HeyTrace19 - Thanks for the "thumbs up" on Tholen. And thanks, Ayden, for chiming in.
Thanks, too, for those who offered 'corrections.' In fact, as has been stated, any number of surgeons do
not require a therapist's letter. And, WPATH
recommends a letter that it then says
should be required prior to physical intervention. These are suggestions, not requirements. It's up to the surgeon. I can understand why some would require it, especially for younger folks.
I find it intriguing that women are not required to have such documentation for a breast reduction, nor a breast enlargement. But, because of the gender identity issue, and - I suspect - fear of a lawsuit, a majority of surgeons require them for FTM surgery. But, I digress. I did visit a therapist, because I thought I would need a letter. It ended up me spending $300 to educate him. No thanks. At 58, I know who I am and what I want.

Thanks for mention of others' names. I've spent a fair amount of time on transbucket. And, short of researching everyone, just wanted a few others to consider. Thanks, again!
