ANECDOTE

How A Failed Project Became Treehouse Recovery

  • Justin McMillen accidentally became a housing provider after the 2008 crash and pulled many homeless people into his properties.
  • That hands-on rescue work evolved into sober living as he noticed most people he helped were using drugs and needed structure.
INSIGHT

Set Clear Biopsychosocial Targets For Recovery

  • Treating addiction needs explicit biopsychosocial aims rather than generic interventions.
  • Justin argues you must define biological, psychological, and social targets (e.g., optimize brain health, build resilience, restore bonding) to have measurable treatment goals.
ADVICE

Restore Ancestral Habits To Improve Brain Biology

  • Optimize biology by restoring evolutionary-consistent habits like movement, circadian rhythm, and whole foods.
  • Justin uses ancestry-informed targets (fitness baseline, sleep, whole food diet) as concrete biological goals in treatment.
