Why Treat Both Conditions Together?

When substance use and mental health issues occur at the same time, they can intensify one another. If only one condition is addressed, symptoms of the other can undermine progress — leading to relapse or ongoing distress.

Our dual diagnosis program is designed to:

  • Identify and treat underlying mental health conditions.
  • Provide safe, structured support for addiction recovery.
  • Equip clients with coping skills for both mental health and sobriety.
  • Reduce the risk of relapse by creating a comprehensive care plan.
