Integrated Dual Disorders Treatment Program (IDDT)


Outpatient services for adults ages 18 and older with co-occurring mental health and substance use disorders.

Psychotherapy • Dual Diagnosis • Case Management • Mental Health • Substance Use • Counseling


Integrated Services is an outpatient resource for people presenting for treatment with co-occurring substance use and psychiatric disorders. Treatment for such disorders occurs simultaneously and therefore integrates substance use and mental health treatment. This Level I program focuses on abstinence from or significant reduction in use of drugs and alcohol. It also helps clients access affordable housing, primary healthcare, community-based support systems, and entitlements. IDDT also ensures compliance with court ordered treatment.

Services are offered primarily in clients' homes and community locations.
