Each Sunday, with an average of 6 volunteer test counselors and waiting room educators, HIV Prevention Services provides client-centered HIV prevention education and referrals to approximately 50 clients.

The Berkeley Free Clinic has hosted an Anonymous Test Site (ATS) for HIV since 1989 through HPS and the Gay Men's Health Collective (GMHC) in collaboration with the Pacific Center and the City of Berkeley. Anonymous HIV testing means that we do not collect identifying information about any client. All test results are returned in about 40 minutes in person.

HIV Prevention Services and the Gay Men's Health Collective also team up to provide free HIV and Sexually Transmitted Infection (STI) testing and counseling at Berkeley's Steamworks. We have provided weekly services there since 1988.

The HIV Prevention Services Section (HPS) is not currently accepting applications for new volunteers.
