Dedham Visionary Access Corporation's (DVAC) mission statement is to "stimulate a vibrant community reaching and connecting the organizations, neighborhoods, families and individuals of all ages to tell Dedham's many stories- past, present and future. By using media and technology, DVAC fosters meaningful and relevant projects to spark curiosity, nurture creativity and innovation, and fuel life long learning. We facilitate this mission by providing grants, guidance and support resources to impact the quality of life in Dedham."

DVAC was formed to provide a "PEG" (public, educational, and government) access channel for the Town of Dedham. A PEG access center is a combination school and equipment library where individuals are trained how to use TV production equipment, how to make TV shows, and then are provided the free use of equipment and cable channel time to produce and air their shows. DVAC's access center is funded by a small cable license fee of the local cable company's revenues that pay for facility upkeep, utilities, and full-time staff. The staff manages the public resources, train people in TV production skills, and facilitate the telecast of programs on the local channels.

In its initial years, DVAC operated primarily as more of an arts or cultural council, with donations being made to various artists, schools and organizations. For example, DVAC made grants to Dedham High School for the purchase of items, which provided access to video equipment and distribution of video programming.
