Matt Greenfield is the American co-founder of the now defunct ADV Films. Originally an avid fan who ran an anime club in Houston, Texas with David Williams (known as "Anime NASA"). He, Williams and John Ledford founded ADV Films in 1992, which began as an importer of anime, marketing primarily to the existing network of anime fans. He was married to ADV contractor and voice actress Tiffany Grant.
