Mary Salazar


Mary has worked in the HIV prevention field since 2013. She began as an HIV test counselor, and utilized a variety of rapid testing technologies. Her most notable testing experience occurred when she responded to the HIV epidemic in Scott County, Indiana, in 2015, driving a mobile testing unit there from Los Angeles. She created a mobile testing clinic, and conducted street outreach to clients in rural areas of the state, testing scores of clients. The experience underscored Mary’s passion for harm reduction, data-driven public policy, and the importance of providing services to marginalized groups in a manner that is proactive, rather than reactive. She draws on these values in her work leading trainings funded by the California State Office of AIDS, as well as the National HIV Classroom Learning Center. In addition, she develops curricula and webinar presentations on a variety of topics.
