ATRIUM is a 12-week course for people with addiction and/or trauma histories developed by Dusty Miller, of the ATRIUM Foundation. Participants learn to recognize the interactions between trauma (abuse, neglect, etc.) and addictions (substances, food, sex, etc.), how they trigger each other, and how to intervene to stop this cycle. ATRIUM is designed to compliment ongoing therapy, recovery or 12-step work, not to replace it, and addressed the mind, body and spirit.
