About Us

Our History

Alianza began in 1993 to respond to the need for an HIV resource center in the southeastern communities of New Mexico. Individuals came together to help with the questions, fear, and pain that many faced at the time. Shortly after, in 1996, Alianza began outreach to bring attention to the need for syringe exchange programs for those who inject substances. With an initial response of nearly 400 people who inject substances and their allies, it was clear that sharing needles was far too common. In 2012, Alianza celebrated the opening of a second office location in Las Cruces, NM.

What began as a support group transformed through the hard work of many hands over the years to become a multi-operational and diversified organization serving the needs of many.


We lovingly operate support groups and educational group interventions to encourage conversation about difficult topics. We offer a food assistance program, on-site medical clinic, transportation assistance for medical appointments, health insurance navigation and more.

Harm Reduction and Prevention

We run stigma-free syringe exchanges, free HIV, syphilis and hepatitis C testing without any judgement, and a PrEP linkage program that guides people in need to the prevention methods that work for them. Our MAT (medication assisted treatment) linkage helps healthcare providers be able to use evidence-based treatments for people who use substances while also providing people who use substances information they can use to find treatment.


We operate housing assistance for qualifying individuals throughout New Mexico to see people moving from the streets in to homes that foster healthier living opportunities. Funding from federal and state sources allows applications to receive rental assistance, utility assistance, and more.
