About MRS Rehab
For 24 years, MRS Rehab has transformed moments of crisis into foundations of lasting calm for families across Lincoln and Placer County.
Our Story
In 2002, Dr. Margaret Reyes-Santos buried her younger brother. He was 31, bright, generous, and six years deep into an opioid addiction that no treatment center in Northern California seemed equipped to handle. Every facility he entered treated the substance but ignored the panic attacks, the childhood trauma, the fractured family relationships that kept pulling him back into use. After his funeral, Margaret stood on the front steps of the church on G Street in Lincoln and made a promise to the family gathered around her: she would build the kind of place that could have saved him.
She sold her private practice, partnered with two addiction medicine specialists, and opened the doors of MRS Rehab at 537 G Street. The founding principle was simple but radical for its time: treat the whole crisis, not just the chemical. That meant hiring trauma therapists alongside detox nurses, opening a family lodge so loved ones could participate in treatment from the start, and creating a harm-reduction framework that met patients where they stood rather than demanding perfection on day one.
Twenty-four years and over 13,000 patients later, that promise still guides every decision we make. Our 45-bed facility has grown from a converted Victorian house to a modern treatment campus, but the mission has never shifted. We exist because one family lost someone they should not have lost, and we work every day to ensure yours does not face the same outcome.

What Our Alumni Say
I was a marketing director who drank behind closed doors for eight years. When my firm found out, I thought my career was finished. MRS Rehab built a schedule around my professional obligations so I could maintain my responsibilities while actually getting better. The CBT sessions helped me identify the triggers hidden inside my high-pressure workdays, and the private rooms gave me the space to process without judgment. Fourteen months sober now, and I just got promoted.
I was 23 and already on my way to losing everything. Opioids had taken over my sophomore year and by the time I dropped out, I barely recognized myself. Walking into MRS Rehab felt like the first honest thing I had done in years. The group therapy sessions with other young adults showed me I was not the only one fighting this battle at my age. The outdoor fitness area became my morning ritual, and the counselors helped me plan a future I actually wanted to wake up for. I re-enrolled last semester.
Four treatment centers in seven years. I had almost accepted that I would never get clean. What made MRS Rehab different was the dual diagnosis work. No one had ever treated my anxiety alongside my methamphetamine addiction before. The EMDR sessions unlocked trauma I did not even know I was carrying. The harm-reduction approach let me build momentum instead of feeling like a failure for not being perfect on day one. Two years clean this March, and my family is back in my life.
