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

At Valley Streetz, we are dedicated to providing equitable and compassionate care to those who are often overlooked in our healthcare system. Our harm reduction services are available to those who need it most, and our team is committed to making a positive impact in the lives of our patients.​

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

Our team works tirelessly to promote public health and safety through a variety of initiatives. By working together with community members, we can lower infectious disease rates and opioid overdoses and create a healthier and safer future for all.

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.
