Cathrine Kellison's career as a writer/producer spanned two decades, and included an eclectic range of projects - from a CBS special to a PBS documentary, from corporate image pieces for IBM to behind-the-scenes celebrity interviews for MGM, from a kids' piece on recycling to educational films for teachers. She produced, written, and/or directed hundreds of hours of broadcast and non-broadcast programming for television and various avenues of new media. Starting as a writer of feature-length scripts in Hollywood, Ms. Kellison moved into producing for NBC and, later, United Artists in New York City as Director of Creative Services. She then went independent, starting her own small-but-meaningful production company, Roseville Video. Ms. Kellison began teaching producing for television and film at New York University's Tisch School of the Arts in 1994, and now taught and advised students of media studies in NYU's Gallatin School of Individualized Study and SCPS. Ms. Kellison worked fluently as a writer, authoring or co-authoring a number of books and articles primarily in the Affective Education domain and in mathematics education reform. Ms. Kellison was a member of the Producers Guild of America, the Writers Guild of America, the Independent Documentary Association, and won numerous industry awards, including two WGA awards for Outstanding Achievement.
