Sarah GowanSarah 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 webmaster/designer, graphic artist, materials editor and, because she has read more computer manuals than anyone else, default IT manager.
