I go by an alias, and the only people outside of work that know my legal name is my pastor (for background check) I go by that for a few reasons. For one, I'm a gender queer. Some people wouldn't guess that but mainly because they don't care and don't ask, which is the way I like it. But my known name is neutral. It's also a name I consider sacred. And the secrets behind that name are guarded by close friends. I'd never have it as a legally changed name, just an alias.
