He then shifted his academic focus to film, obtaining a master's degree in cinema from a university. It was during this time that he began exploring voice acting by founding an association called GotohWan, which served as his entry point into the profession through various workshops and experiences.

Guitard has built an extensive career lending his voice to numerous characters in animated series, primarily for French-language dubs of Japanese anime.
