  • Out Patient

    Outpatient treatment describes all addiction treatment that is not residential. Patients live at home while undergoing rehab.
  • Family Program

    Research shows that the odds of successful, sustained recovery from addiction are far higher when family members and loved ones are involved in treatment. Drug and alcohol addiction often have genetic roots, whether related to substance abuse, mental illness or both. Family dynamics also play a role and, often, family members are the first to realize a loved one has developed an addiction. Also, it’s important for family members to understand and embrace the lifestyle changes that are required to sustain recovery.
