About MHS Rehab
Learn about our mission, our team, and our commitment to your recovery.
Our Story
MHS Rehab was established in 2013 when a coalition of Inland Empire behavioral health advocates saw the need for an addiction treatment center that truly reflected Chino's diverse, hardworking values. What began as a modest 18-bed program near downtown Chino quickly earned a reputation for providing affirming, high-caliber care to people of all backgrounds.
Over 13 years of steady growth, MHS Rehab has expanded to 44 beds and a staff of 92 professionals, serving more than 7,600 individuals. We developed specialized tracks for LGBTQ+ clients, unhoused individuals transitioning into stable recovery, and multilingual patients — each program shaped by direct input from the communities we serve.
Under Executive Director Dr. Eleanor Chang, the center continues to pioneer urban recovery models that pair clinical rigor with radical empathy. Her vision of care that dismantles stigma and embraces identity has positioned MHS Rehab as a trusted resource throughout the Inland Empire and beyond.
Our Mission
MHS Rehab is committed to providing affirming, evidence-based addiction treatment that respects the dignity and identity of every individual. We investigate the underlying drivers of substance use disorder, design therapies around each person's lived experience, and cultivate practical tools for lifelong sobriety.
Deeply rooted in Chino's diverse community, we hold that recovery flourishes when people feel genuinely seen — by skilled clinicians, by peers who share similar struggles, and within a facility that celebrates rather than erases who they are.
Treatment Philosophy
At MHS Rehab, we recognize addiction as a complex medical condition shaped by biology, environment, and lived experience — never a moral failing. Our clinical framework is guided by three foundational commitments:
Evidence-Informed Innovation: We employ Cognitive Behavioral Therapy, Dialectical Behavior Therapy, motivational enhancement, and medication-assisted treatment — each validated by robust clinical research. Our outcomes team continually reviews data to refine protocols and adopt emerging best practices.
Identity-Affirming Care: Chino's strength is its diversity. Our programs are designed to be LGBTQ+-inclusive, culturally responsive, and trauma-informed so that every client receives care that honors their background, orientation, and personal narrative.
Individualized Recovery Pathways: No single blueprint fits every person. Our clinicians conduct thorough biopsychosocial assessments and collaborate with each patient to build a recovery plan that accounts for their strengths, risk factors, family dynamics, and long-term goals.

Alumni Testimonials
"I arrived at MHS Rehab in March 2025 after years of failed attempts elsewhere. The staff immediately made me feel welcome without a trace of judgment. Dr. Adeyemi adjusted my detox medications with a precision I had never experienced, and the evening group sessions gave me language for emotions I had been drowning with alcohol. Eleven months clean and counting."
"As a queer woman, I was terrified of entering treatment. MHS Rehab was the first place where my identity was not just tolerated but genuinely celebrated. The dual diagnosis team helped me understand how untreated depression had been fueling my substance use. I left with a sense of self I hadn't felt since I was a teenager."
"The IOP program let me keep my job in the Mission District while finally confronting my addiction head-on. I commuted to the center three evenings a week, and every session challenged me in the best possible way. Veronica Solis has a gift for seeing through excuses while making you feel like she genuinely cares. Two years sober this February."
"My family nearly fell apart before I checked into MHS Rehab. The residential program gave me structure I desperately needed, and the family therapy sessions rebuilt bridges I thought were gone forever. Recovery can be overwhelming in recovery, but the aftercare team connected me with local support groups near downtown Chino that have become my anchor."
