Sarah Gowan Sarah Gowan has been with SRI since 1984, when she was hired as a scenic artist before the ink had dried on her Temple University theater degree. She's worn many hats since, including paint charge, bookkeeper and office manager. Most recently she serves as the company materials editor, graphic artist, webmanager and, because she has read more computer manuals than anyone else, default IT manager.

In her life outside of SRI she performs with a percussive dance group, and plays for contra, square and English country dances - activities which mortified her two children until they grew up and thought she was cool again. When asked how she manages to pack so much into her busy life she replies, "Easy - don't clean." email Sarah
