About Tree House Recovery PDX
Operated by people in recovery, Tree House Recovery in Costa Mesa, California, treats clients struggling with alcoholism or drug addiction. They employ their mind-body-social method to create a holistic program that was created by Founder Justin McMillen. The goal is to “take the struggle of getting sober and use it to bond people together. In that struggle, there emerges a camaraderie made of trust, vulnerability, success, and support that feels like home.” Treatment bridges multiple levels of care, featuring a primary men’s partial hospitalization program (PHP) with housing, alongside a co-ed intensive outpatient program (IOP).
Follow 8 Connected Steps to Rebuild Mind, Body, and Social Ties
Instead of putting bandaids on symptoms, the Tree House approach looks at the root causes of addiction: physical breakdown and feeling isolated. They work to heal the mind, body and social factors driving addiction using an 8-part curriculum:
- Addiction education (relapse prevention and the science of addiction)
- Process groups (talking things out with peers)
- One-on-One therapy (2 private clinical counseling sessions per week)
- Writing therapy (2 one-on-one trauma-informed counseling sessions per week)
- Fitness-based experiential therapy “ESM” (daily workouts to help balance neurochemistry)
- Team-based experiential therapy “ABIT” (action-based MMA meant to help clients bond, and build trust)
- Yoga therapy (meant to help clients regulate emotions through movement, breathwork, and meditation)
- Adventure therapy “Recovery in Action” (clinician-guided events in the real world like camping, surfing and 5ks meant to help experience what a healthy sober life can be)
Five days a week, clients sweat it out in group workouts. Forcing the body to move acts like a hard reset and can help improve sleep, lower anxiety, and speed up the healing process of post-acute withdrawal. When clients face these daily challenges alongside other people, the focus shifts to what a person can handle right now, making it easy to realize they are not defined by their addiction.
Enjoy an Environment Designed to Ground and Support the Mind
Set in a vibrant Portland neighborhood, clients at Tree House cook together like a family in full kitchens, play music in comfortable lounges, or relax in the backyard under the Pacific Northwest sky. The high-energy gym space transitions into a peaceful studio for restorative yoga twice a week. Through breathwork and meditation, individuals learn to quiet their racing thoughts and sit comfortably in silence, balancing out the active portions of their day.
Access the Fitness, Counseling, and Tools That Keep Clients Grounded
Instead of rushing back into daily life, individuals can transition into structured housing for up to a full year, giving them room to hold down regular jobs without losing their footing. Through the co-ed intensive outpatient program (IOP), both men and women keep accessing the vital components of recovery: like group fitness, relapse prevention, and group counseling, so they can rebuild their lives while being anchored to a community.
