The Millard Sheets Center for the Arts began as the Fine Arts Program of the L.A. County Fair — art exhibitions have been an integral part of the Fair since its founding in 1922. Each year, the exhibits produced for the Fair have featured artists from not only Los Angeles, but also California, the nation, and throughout the world, and have presented contemporary as well as historical art in a variety of styles and media.

In 1998, the Millard Sheets Center for the Arts was incorporated as a nonprofit organization with the purpose of helping to fill a gap in the cultural opportunities available for Pomona-area residents. Since then, the gallery’s vision is to become a year-round arts venue, offering the people of Southern California an opportunity to experience diverse and progressive art exhibitions combined with lively educational programs, with the goal of encouraging new generations of art enthusiasts.
