What hasn't he done? Stephen was a Klingon captain in the 2-part Trek episode that had Spock on TNG ... He's the lead in the sci fi series Tripping the Rift (loving it!), he's on the West Wing, King of the Hill, American Dad, Dodgeball, he was Milton on Office Space, he's just everywhere, and he's never a disappointment.
Stephen does not have an official website
