About CLARE Matrix DBA Matrix Institute
CLARE Matrix — also known as Matrix Institute — is a licensed substance use treatment center on the Westside of Los Angeles offering a full continuum of care, from medical detoxification through residential treatment and outpatient programs. Operating since 1970, it serves men, women, people with co-occurring disorders, and individuals connected to the criminal justice system across Santa Monica, Mid-City Los Angeles, and Ontario.
CLARE Matrix, doing business as Matrix Institute, has been part of the Los Angeles recovery community since 1970. Located at 909 Pico Blvd in Santa Monica, this California Department of Health Care Services-licensed and certified substance use treatment center draws clients from across the Westside of Los Angeles, Mid-City Los Angeles, and Ontario — offering a structured continuum that meets people at different points in their recovery journey, not just at the moment of crisis.
The center's levels of care span the full recovery spectrum. Medical detoxification provides a supervised starting point for those who need it, followed by residential treatment programs running 30 to 90 days. For people transitioning out of residential care or those who never required it, CLARE Matrix offers both intensive outpatient and standard outpatient programming. The center is also certified as an Opioid Treatment Program, a designation that reflects a specific clinical and regulatory commitment to treating opioid use disorder within its outpatient framework.
CLARE Matrix is organized around the Matrix Model — a structured, research-developed approach to substance use treatment that integrates scheduled sessions, skill-building, and ongoing accountability. Certified by the California DHCS, the center also provides recovery support services and case management as part of its aftercare framework, helping clients maintain gains after completing a primary program. These services are designed to extend clinical support into daily life rather than ending at discharge.
The center serves men and women, people managing co-occurring mental health and behavioral health conditions alongside substance use disorder, and individuals affected by the criminal justice system. That breadth of focus — paired with a continuum that runs from detox through aftercare — makes CLARE Matrix a meaningful option for families and individuals seeking a long-term recovery partner in the greater Los Angeles area, not just a short-term intervention.
A Full Continuum of Addiction Treatment in Los Angeles
CLARE Matrix offers one of the more complete addiction treatment continuums available on the Westside of Los Angeles. Rather than providing a single level of care, the center is structured so that clients can move from medical detoxification into residential treatment and then step down into intensive outpatient or standard outpatient programming — all within one organization. That kind of continuity matters for long-term recovery, where relationship with a consistent treatment team and community often influences outcomes as much as any single program.
Residential treatment at CLARE Matrix runs 30 to 90 days, providing the extended time in care that research consistently links to better recovery outcomes. For individuals who complete residential care or who enter the program at an outpatient level, both intensive outpatient and outpatient tracks are available. The center's Opioid Treatment Program certification adds a specialized layer of clinical capacity for clients managing opioid use disorder within the outpatient setting. Together, these levels of care allow the treatment plan to evolve alongside each person's recovery rather than ending at a fixed point.
The Matrix Model: A Structured Approach to Substance Use Treatment
CLARE Matrix takes its name in part from the Matrix Model, the clinical framework at the center of its programming. The Matrix Model is a structured outpatient approach developed specifically for substance use treatment, combining elements of behavioral therapy, family education, group support, and individual counseling in a defined sequence. It was developed and refined in part by researchers affiliated with the Matrix Institute itself, giving CLARE Matrix a direct institutional connection to the model's origins.
This structured approach means that clients and families engaging with CLARE Matrix can expect a consistent, organized program rather than an improvised one. The model's emphasis on accountability, skill development, and regular contact is well-suited to the longer arc of recovery — not just the initial weeks of treatment, but the sustained effort that follows. For people evaluating a recovery center as a long-term partner rather than a short-term solution, that kind of clinical consistency is a meaningful differentiator.
Aftercare and Recovery Support Services
Completing a residential or outpatient program is a milestone, not an endpoint. CLARE Matrix provides recovery support services and case management support as part of its aftercare framework, extending the center's involvement beyond the formal treatment period. Case management helps clients navigate the practical dimensions of sustained recovery — connections to community resources, coordination of continuing care, and support through the transitions that follow treatment.
For families and individuals evaluating addiction treatment options in Los Angeles, the presence of structured aftercare signals that CLARE Matrix is designed around the full recovery journey, not just the acute phase. Recovery support services create a bridge between clinical treatment and independent community life, which is where the real work of long-term sobriety takes place. These services are available to the populations the center serves, including people with co-occurring mental health disorders and those navigating reentry from the criminal justice system.
Who CLARE Matrix Serves
CLARE Matrix serves men and women across a range of circumstances and treatment needs. The center's programming is designed to accommodate people managing co-occurring mental health and behavioral health conditions alongside substance use disorder — a population whose needs often go underserved in settings that treat addiction and mental health as separate concerns. By addressing both within one continuum, the center provides a more integrated starting point for recovery.
CLARE Matrix also specifically serves people affected by the criminal justice system. Whether clients are court-referred, on probation, or navigating reentry, the center's experience with this population means its clinical and case management teams are familiar with the intersecting pressures that can make sustained recovery harder. Service extends across the Westside of Los Angeles, Santa Monica, Mid-City Los Angeles, and Ontario, and the center can be reached at (866) 452-5273 Monday through Friday, 9 AM to 5 PM.
