The Multicultural AIDS Resource Center (MARC) was a subsidiary project of the Multicultural Training Resource Center (MTRC). MTRC was created in 1984 by Sala Udin, an experienced community organizer who was interested in helping people of color to increase skills and knowledge in community organizing. MARC was created to train the statewide contractors that serve people of color, about multicultural approaches to AIDS education and prevention. Its two main programs were Abraxas, which developed a multi-cultural HIV Antibody Test educational campaign, and a three year state-funded Technical Assistance Program.

Besides these two primary operations, MARC staff were key players in developing strong advocacy for AIDS services appropriate to the diverse cultures of people of color in the San Francisco Bay Area. Records selected for retention document each of these activities.

As other organizations that focused on gay men of color grew and began to secure more service contracts, and reporting requirements became more demanding, MTRC found itself increasingly under-funded and out of step. Both MARC and the Multicultural Training Resource Center closed in early 1993.
