Dodge college
Dodge College

Dodge College has more than 1,405 film and media arts students (1,122 undergraduate and 283 graduate students), 40 full-time faculty and 80 adjunct faculty. The program is small enough to be overwhelmingly hands-on, yet well-equipped enough that students rarely have to wait for a camera or AVID station.

Students at Dodge College of Film and Media Arts, study under master storytellers who’ve honed their crafts over a lifetime of award-winning work and who have a combined filmography of more than 300 feature films — a record unmatched by any other film school in the country.
