Learn MoreTwo Decades of Addiction Care on East Fourth Street, Ontario
PMHL Rehab opened in 2003 because a nurse practitioner working an Ontario emergency department was tired of watching the same five patients cycle back through her trauma bay each month. Twenty-three years and 11,200 patients later, the program she built still organizes its work around the question that drove its founding: what does treatment look like when it is built by a clinician who has watched untreated addiction kill people?
Welcome to PMHL Rehab
PMHL Rehab sits on East Fourth Street in downtown Ontario, in a converted three-story building that became our permanent campus in 2007. Our 54-bed residential program, dedicated medical detox wing, and full outpatient continuum are staffed by 114 clinicians whose work is coordinated through a shared treatment record - one chart, one plan, one team across every shift.
Twenty-three years of operations and 11,200 patients later, the founding orientation has not shifted: every patient who walks through our doors is treated as an adult making a hard decision, not a problem to be managed.

Why Choose PMHL Rehab
Built by a Nurse Practitioner
Founder Lourdes Marquez-Hopper, NP, opened PMHL in 2003 after a decade of emergency-department work. The clinical protocols still trace back to questions she encountered triaging untreated overdoses - the founding orientation has not changed in twenty-three years.
Dignity Is a Clinical Standard
Dignified treatment is not a tagline. Staff are trained to never use language that compounds shame, never require a patient to explain their relapse history twice, and never document in ways that read as judgment.
114 Clinicians, Shared Record
Medical, psychiatric, therapy, and case-management staff document in a single chart and meet three times weekly per resident. Information does not fall between the shifts that often leave patients invisible.
Trauma-Informed Throughout
From intake questions to room lighting to how we deliver difficult news, trauma-informed practice is the operating system. Annual staff training and four certified trauma specialists on the clinical team keep that standard real.
Balanced Recovery Schedule
Days are organized in equal parts: clinical, physical, creative, and reflective. Therapy and medication are core, but so are movement, the meditation room, and the unhurried hours that early recovery actually needs.
In-Network With Eight Major Plans
Aetna, Blue Cross Blue Shield, Cigna, Medicaid, Medicare, Magellan, WellCare, and Humana. Verification typically completes in under an hour, and the cost picture is shared honestly before any commitment.
Our Treatment Programs
Residential Treatment
30 to 90 days in our 54-bed residence on East Fourth Street. Days are built around a balanced-recovery schedule - equal time for clinical work, physical movement, creative expression, and quiet reflection.

"My wife had stopped asking. My adult kids had stopped calling. By the time I drove myself to PMHL on a Tuesday morning, I was certain I would last about six hours before signing myself out. The intake nurse - someone who had clearly been doing this for years - did not try to sell me on staying. She walked me through what the next 72 hours would look like in specific terms and then said, very plainly, that she would not be offended if I left. Two days later I had decided to stay. Forty-five days after that I walked out of residential as a different person."
- Anthony R., residential alumnus, 2024
"I came through PMHL in 2019 with twenty years of drinking and a marriage that was about to end. The treatment worked. The marriage held. What I did not expect is what happened after - I started volunteering at the alumni Saturday meetings, then trained as a peer support specialist, and now I work part-time on the admissions team helping people make the same call I almost did not make. Five years sober, and the giving back is part of what keeps the recovery alive."
- Carmen V., residential alumna 2019, peer support specialist
"Eighteen years on a medical-surgical floor in Riverside. The pandemic took the joy out of nursing for me, and the medication cabinet I had access to all day became a problem I could not name out loud. Walking into PMHL as a healthcare worker is its own difficulty - you know what every chart entry means. The clinical team here treated me as a colleague making a hard decision, not a patient being managed. They built a peer cohort with two other nurses for the first weeks. I am back nursing, in a different role, sober."
