Justin McMillen is the CEO and founder of Tree House Recovery, a national addiction treatment organization, and THARI, a healthcare management and research organization focused on building more effective, human-centered approaches to substance use disorder treatment. His work has helped shape care models used by elite military units, first responder communities, and public health systems across multiple states.

Justin brings lived experience together with systems-level thinking and scientific curiosity. In addition to clinical innovation, he has led large-scale infrastructure efforts that have helped thousands rebuild stability, purpose, and direction in their lives.

On the podcast, Justin explores the human side of discipline, stress, identity, and growth through honest conversations with people who’ve lived at the edges of experience. The focus isn’t performance for its own sake—but what actually carries over into everyday life, long after the hardest chapters are behind us.
