Sarah Hendrickx is one of the best speakers I've ever heard.
Most of the YouTube videos you'll find are recordings of talks she has given to non-autistic people (caregivers and 'experts').
The video I link to below, is the most recent one I could find. In it, she's giving a talk to her peers (other autistic people). It's quite funny, and yet ... she's telling it like it is.
I've heard her mention a couple of times that she has written some books as well. I'll try to track them down. They might be informative (and hopefully funny) as well.
Sarah has her own business ; it is called 'hendrickx associates'.
