Accessibility Iron Man, Derek Featherstone is a Canadian force to be reckoned with. A former high school chemistry teacher turned web accessibility expert, Derek has made it his business to educate people both on and off the stage. He toggles his time between his business, Simply Accessible, world-renowned speaking, grassroots coalitions and consulting gigs, as well as authoring some helpful books. To top it off, he’s a Fit Geek and he’s completed the IronMan triathlon. Three times. What a punk.
