I couldn't find it mentioned anywhere on the site, but where are they based out of? I have a friend whose sister is autistic and whose mother became a speech pathologist because she couldn't find any "good" ones in the area (and have done some technical work there in the past). However, I'm one of those unwilling to relocate right now types.

I'm not affiliated with them, but I know the founders are looking high and low for the right person.
