Valley Streetz
Harm Reduction & Syringe Service Program
Our Principles
We aim to create a safe and inclusive environment for our community members to access harm reduction services, with a foundation of autonomy and radical love. You are safe with us.

Equity

Empowerment
We are committed to improving public health outcomes in our community and empower individuals with lived experience to play an active role in our work. By hiring those who have been directly impacted by public health issues, we ensure that our efforts are informed by the perspectives and needs of the people we serve.

Community

Radical Love
We are a public health organization that is committed to providing compassionate care to everyone in our community. Every person deserves to be treated with dignity and respect, and we strive to create an environment of radical love and empathy.
Our Mission
Valley Streetz Harm Reduction Program empowers individuals through evidence-based harm reduction practices that promote social justice, reduce the spread of infectious disease, prevent overdose-related deaths and improve quality of life, by addressing the underlying structural factors that contribute to harm.
We envision a future where addiction services are accessible, equitable and stigma-free, with the recognition of the trauma and social hurdles experienced by people with addiction.

“We must learn that passively to accept an unjust system is to cooperate with that system, and thereby to become a participant in its evil.”
Dr. Martin Luther King Jr.
