If 12-step or traditional treatment has failed you before, there's another way to get sober.

How It Works
Addiction isn't a character flaw, and you're not weak. The same relentless drive that made it impossible to stop becomes your greatest advantage once it's pointed in the right direction. We don't pile on restrictions. We teach you to harness it and get more out of life.
Structured fitness, adventure work, ice baths and sauna are the treatment itself, with clinical reasoning behind every session. Training restores the brain chemistry addiction ran down, and it scales to wherever you're starting, even if that's zero.
Daily addiction education and more one-on-one clinical time than the outpatient norm teach you what's actually happening in your brain, so cravings, anxiety and relapse patterns stop being mysteries and become problems you know how to solve.
You do all of it inside a small team that trains, eats, and does the hard work together. Isolation is what drives relapse, so connection isn't left to chance here. It's built into the treatment day, and it's why graduates stay in each other's lives.
We built the program around what your life looks like after you leave, and we measure it:
Based on self-reported surveys of Tree House Recovery graduates. Every recovery is different and individual results vary.
You don't have to have it all figured out
We pride ourselves on helping people make real, positive change. Don't let the active, physical side scare you off. We don't expect anyone to feel great about their physical health when they start. Come as you are, and we'll build from there, together.

Our Program
Abstinence is just the jumping-off point. To make change last, you have to build a life you're excited to lead, so each person's program draws from eight integrated, evidence-based modalities that rebuild the whole person.
Private, focused sessions with licensed clinicians, built around your history, your goals, and your pace.
Daily, structured training that rebuilds the brain chemistry addiction wears down and restores real discipline. It scales to any starting point, even if you haven’t trained in years.
Real-world, action-based adventure challenges tied to brain science and team dynamic. A differentiator no traditional center can match.
Learn exactly what addiction does to your brain and body, so cravings, triggers, and relapse patterns stop being mysteries and start being problems you can solve.
Honest, guided conversation inside a small circle of peers who get it, where you practice being open and accountable instead of going it alone.
Process trauma and rewrite the story you tell yourself, turning painful history into a foundation for change.
Practical tools to calm the nervous system, sit with discomfort, and quiet the cravings and anxiety that used to send you back to using.
You practice new skills in real situations before you leave, so recovery holds up in everyday life, not just inside the treatment room.

Getting Started
Speak with a real admissions specialist. No pressure, no judgment, just a conversation about what's going on.
We'll confirm your benefits and walk you through coverage and options, confidentially.
We build a personalized plan and welcome you onto the team, often within days.
Paying for Treatment
We work with most PPO insurance plans and will verify your benefits before you commit to anything.
Logos shown as placeholders, confirm in-network carriers before launch. Most PPO plans accepted. Coverage varies by plan and policy.
What We Treat
These are some of the substance issues we specialize in, but nobody's story fits neatly into a category. Substances are usually only part of the picture. We take the problems in front of you seriously, and we work with you to get underneath them, addressing the core issues so the change you make actually lasts.
Questions, Answered
Most major PPO plans are accepted, and we'll verify your exact benefits in minutes.
Our Nashville program is a coed treatment community for adult men and women struggling with drug or alcohol addiction. We welcome clients from California and across the country who are ready for a better path to lasting recovery.
Instead of treating addiction in isolation, we rebuild the whole person through an 8-element, evidence-based curriculum, including fitness therapy, writing therapy, and a team built on accountability, so recovery actually lasts.
Often within days. The first step is a quick, confidential call. We'll talk through your situation, verify insurance, and help you take the next step as fast as you're ready.
We offer a full continuum including Partial Hospitalization (PHP), Intensive Outpatient (IOP), and ongoing outpatient and aftercare support, and we have resources available if you need a sober, supportive place to live. We'll recommend the right starting point based on your needs.
We don't run a medical detox on-site, and many people don't need one. For those who do, we'll help arrange a safe detox first and coordinate a smooth hand-off into our program the moment you're medically cleared.
Most of our calls come from parents, partners, and friends. We'll walk you through the options, what coverage looks like, and how to start the conversation, with no pressure and complete confidentiality.
Completely. Your conversation and information are private and HIPAA-secure. There's no obligation and no pressure, just honest answers about your options.
You don't have to do this alone. Talk to a counselor who gets it. Confidential and available right now.
