Our Story

We were inspired to open our first BIOS site in Palm Springs, CA in the spirit of expanding clinical research options for the Coachella Valley, and in recognition and respect of the many long-term survivors and persons living with HIV (PLHIV) in the region.

Our passion is to make HIV clinical trials accessible to regions with unmet needs. To us, this means establishing research sites in areas with a high incidence of HIV and with diverse populations. We wholeheartedly believe our efforts will encourage health equity and diversity in clinical research, and ultimately result in broader applicability for investigational new agents.

We believe that clinical research is a community-based effort. Therefore, we welcome partnerships with local clinics and organizations supporting PLHIV so we can successfully establish research sites in regions that need them most. We are focused on engaging communities of color and diverse genders, sexualities, races, and nationalities. Contact us for collaboration or to join our network.
