The Last House offers long-term sober living for young adult men (ages 18-30), combining our sober housing with integrated addiction treatment programs in Los Angeles. Residents have access to partial hospitalization programs (PHP), intensive outpatient programs (IOP), and outpatient addiction treatment from Thrive Treatment while living in a supportive environment.
Â

Thrive Treatment is an addiction treatment center that delivers outpatient addiction and mental health services with treatment facilities in Santa Monica, Culver City, and Woodland Hills.Â
As The Last House clinical campus, Thrive provides coordinated, evidence-based care for substance use disorders (SUD) and co‑occurring mental health conditions. Thrive offers dual‑diagnosis treatment for men managing addiction, treating psychiatric conditions that range from depression, anxiety, bipolar disorder, to substance‑induced psychosis.
Thrive’s program offers structured, measurable skill development and uses research-supported therapies that reduce relapse and improve functioning. With over 30 years of combined clinical expertise, the Thrive team brings a direct, compassionate approach to addiction treatment and mental health care across all levels of our outpatient structured programming.
Thrive Treatment offers structured outpatient treatment specifically designed for men living in sober living houses. Programming provides a predictable clinical schedule that supports early recovery while allowing sober living residents to practice skills in real‑world settings.
Thrive structures its PHP and IOP programs around evidence‑based therapies. Clinicians are specialists in cognitive‑behavioral therapy (CBT), dialectical behavior therapy (DBT), motivational interviewing (MI), and medication management. Staff help residents identify self‑defeating patterns and equip them with practical skills that support long-term recovery.
Families also work together with the staff in family therapy sessions to reinforce boundaries, strengthen communication, and support reintegration planning. Additionally, Thrive provides life skills development, vocational and academic reintegration, and peer and alumni mentorship. Teams maintain close coordination, keeping expectations and milestones consistent across housing and clinical settings.

Thrive provides multiple levels of outpatient care designed to support a structured transition from intensive treatment to independent living. Over years of working with young adult men, Thrive’s substance abuse treatment program has developed a clear clinical progression. We meet residents where they are and move them forward at a pace that supports lasting recovery.
PHP is the most intensive level of outpatient care Thrive offers, running 5 days per week. Clinicians deliver individual therapy, group therapy, and clinical skill-building within a structured daily schedule that keeps residents engaged and accountable during the most vulnerable stage of recovery.
Most Last House residents enter at the PHP level, typically following detox or inpatient treatment. The Last House provides transportation to and from the clinical campus throughout this phase. Residents generally spend 1-4 months in PHP before clinicians move them to the next level of care.
IOP is a step‑down from PHP that provides frequent, structured therapy. It allows residents greater flexibility to begin working or attending school.
Clients attend therapy several days per week (commonly 3-5 days) and continue working on the skills learned at the PHP level of care. The lighter time commitment allows residents to begin working, attending school, or taking on community responsibilities while still engaging in consistent clinical treatment.
Residents who complete IOP continue their recovery through outpatient therapy and aftercare programming. Clinicians focus on relapse prevention, ongoing recovery support, and the clinical work needed to sustain long-term recovery after previous clinical interventions.
Thrive maintains active involvement with residents at this stage, ensuring the transition toward autonomous living happens with consistent clinical support in place. Aftercare reinforces accountability and helps clients apply treatment gains in work, school, and everyday life.

Thrive Treatment uses evidence‑based therapies that target the behavioral, emotional, and cognitive patterns driving addiction and co‑occurring mental health conditions. Each therapy serves a specific clinical purpose – whether improving emotional regulation, interrupting self‑defeating behaviors, strengthening decision‑making, or supporting long‑term recovery. Therapists select and combine these approaches based on each resident’s needs, stage of recovery, and level of care, ensuring treatment remains structured and aligned with real‑world functioning.
CBT helps clients examine the thoughts and behaviors that reinforce substance use. Therapists guide clients in recognizing distorted thinking, understanding how those thoughts influence actions, and practicing healthier responses to stress, cravings, and high‑risk situations. The goal is to develop practical coping strategies that sober living residents can use immediately in their daily lives.
DBT strengthens a client’s ability to manage intense emotions without turning to substances. Sessions focus on emotional regulation, distress tolerance, and interpersonal effectiveness. Clients learn concrete skills they can apply during moments of overwhelm, conflict, or impulsivity – situations that often trigger relapse in early recovery.
A trauma-informed approach to therapy helps residents understand how past experiences shape current reactions, coping patterns, and vulnerability to substance use. Outpatient treatment at Thrive emphasizes safety, emotional awareness, and the gradual processing of trauma‑related symptoms.
Mindfulness practices complement this work by helping clients stay present, notice internal cues, and respond with intention rather than reactive behavior. Together, these approaches support steadier emotional functioning during recovery.
Returning to everyday life after detox without clinical support significantly increases relapse risk. Early recovery is often accompanied by anxiety, emotional dysregulation, and an incomplete understanding of the behavioral patterns that led to addiction.
Without structured therapy during this window, clients are more likely to return to substance use — even after completing detox or residential treatment. Structured sober living combined with outpatient care provides regular clinical contact, a consistent therapeutic framework, and the accountability that helps sustain early recovery.
Last House residents start each day with a structured morning routine and spend weekday hours in evidence-based treatment before returning to a substance-free living environment at night.
The Last House and Thrive operate within a shared recovery sense of community that continues long after formal treatment ends. Residents build peer relationships throughout clinical programming and sober living, creating a peer support network that develops through daily structure, shared expectations, and consistent accountability.
Support groups, community meetings, and alumni involvement reinforce that connection. Graduates stay engaged through regular visits, mentorship, and ongoing participation in community activities. Their presence offers current residents practical guidance from people who have already walked through early recovery and the transition to independent living.
Our model is not a short‑term or isolated treatment experience. It is a long‑standing recovery community that residents join and continue contributing to as they progress in their lives. Alumni return regularly, stay connected, and play an active role in the recovery of the men who come after them.

The Last House and Thrive Treatment operate as a coordinated recovery model. Residents live in The Last House sober living homes, attend treatment at the Thrive clinical campus during the day, and return to supervised housing each evening. This setup gives residents consistent clinical care while maintaining the stability of a supervised living environment.
Our model addresses two core needs in early recovery: reliable housing and daily therapeutic support. The program provides transportation between sober living and the clinical campus, ensuring consistent attendance and predictable structure.
This integrated schedule creates a steady rhythm for a resident’s early recovery journey. Clients receive clinical treatment during the day at Thrive’s recovery center, engage with peers in sober living at night, and follow clear expectations across both settings. The result is a coordinated system that supports accountability, community involvement, and the routines needed during the period when relapse risk is highest.
Thrive actively involves family members in the treatment process. The clinical team delivers family therapy to strengthen communication, reinforce healthy boundaries, and address the dynamics that contribute to addiction and recovery.Â
Families receive education on substance use disorder, co-occurring mental health conditions, and what realistic recovery looks like over time. Family support during outpatient treatment produces measurably better outcomes for everyone involved. Thrive equips families with the tools they need to provide consistent, informed support throughout the recovery process.
Sober living provides structured, substance-free housing — a stable living environment with accountability and community. Outpatient treatment provides clinical care, including therapy, psychiatric support, and evidence-based addiction treatment. The Last House and Thrive pair both so that residents receive housing and clinical care simultaneously.
PHP is the most intensive level of outpatient addiction treatment, typically running 5 days per week. It includes individual therapy, group therapy, psychiatric support, and structured skill-building. This program is appropriate for clients transitioning out of detox or inpatient treatment who are not yet ready for a less structured program.
IOP is a structured outpatient program that meets several days per week, offering therapy and clinical support while allowing residents more flexibility than PHP. At The Last House, residents typically transition to IOP after completing PHP — often as they begin work or school.
Yes. This is the core model at The Last House. Residents live in sober living homes and attend treatment at the Thrive clinical campus on weekdays. The two programs are designed to work together, and transportation is provided.
