Majority of my early adult life was spent on the streets, and in and out of DOC. No direction, no vision. When receiving an 8 year bid in my early 30s, I knew something had to change; I came into contact with an ancient manual of Taoism, that expressed personal discipline and balance. I knew by studying this discipline, I could use any obstacle as an opportunity, and utilized that 8 year sentence to learn how to rewire my perspective. Upon my release , I trained in recovery support and earned life coach certification through the Dharma modality, and have now structured my life around helping others in situations that I understand how to recover from.

As part of the Business Development team at Cholla Behavioral Health, I focus on building meaningful partnerships that expand access to high-quality mental health and substance use treatment. I work closely with healthcare providers, community organizations, and referral partners to ensure individuals and families are connected to compassionate, evidence-based care when they need it most.
Prior to joining Cholla, I served as a Peer Support professional with Riverside County, California, where I worked directly with individuals navigating mental health and substance use challenges. That experience strengthened my understanding of the real-world barriers people face when seeking care and reinforced the importance of connection, advocacy, and trust in the recovery process.
I have also worked with Young People in Recovery, a national nonprofit dedicated to empowering young adults in recovery through education, advocacy, and community engagement. This work deepened my commitment to recovery-focused systems of care and community-based support.

My name is Savarra Valdez, and I have been working in behavioral health and addiction recovery for over five years. I consider myself a lifer in this field because recovery isn’t just my profession—it’s my personal journey. I fell into addiction as a teenager, made some painful choices, and hit rock bottom. But through those struggles, I found myself, rebuilt my life, and discovered a passion for helping others do the same.
Today, I am proud of the person I’ve become and the life I’ve created. My experiences allow me to connect deeply with the people I serve, offering both professional guidance and genuine empathy. I specialize in supporting individuals with co-occurring challenges, navigating legal and resource systems, and empowering clients to take steps toward stability and growth. Whether I’m facilitating groups, advocating in court, or sitting one-on-one with someone in crisis, I bring compassion, resilience, and a commitment to walking alongside them.
Fun fact, my favorite saying captures the heart of my work: “When you can’t look on the bright side, I will sit with you in the dark.”
