UK psychotherapist Bob Withers has been in practice for more than 30 years. Late last year an opinion piece he wrote for a British newspaper attracted considerable attention.

He readily admits that the proportion of non-binary or gender non-conforming patients he sees is quite small and that he's not a specialist in the area, but says that living in Brighton - a city with a large LGBT scene - has meant he's seen and supervised a several people who've been in various stages of transition. …
