Tree House Founder and CEO
After years of battling his own addiction, Justin McMillen set out to help others recover from addiction. In 2008, he established Tree House Sober Living, an organization dedicated to sheltering those new in recovery without anywhere else to go. After spending years watching people recover only to relapse in an endless cycle, Justin began studying substance use disorder. The sober living residence became a laboratory for his research that would ultimately lead to today’s most innovative addiction treatment solution.
When Justin established Tree House Recovery in 2013, he based its treatment approach on his research and his own success with overcoming addiction. To further improve the program, he assembled a team of addiction treatment innovators who had redefined what drug and alcohol treatment should look like. This brain trust created, among other things, our guiding principle for recovery—that there is a recipe for healthy living that leads to long-term, sustainable sobriety. We teach clients to live this recipe like a lifestyle, and it has led to client success rates that are far exceeding what the addiction treatment industry has seen in the past. Our approach aims to transform how addiction and treatment are thought about, talked about, and conducted across the nation.
As CEO, Justin is on the front lines as he leads his team and clients forward at Tree House. Justin has teamed up to fight addiction on a national level with the author of Spark and Harvard Medical School’s Professor of Psychiatry, John J. Ratey, MD. He now serves as a Sparking Life Addiction Recovery board member to bring awareness of the effectiveness of exercise as a tool to treat addiction.
