The Substance Use Disorder IOP (Intensive Outpatient Program) at Doorways is a substance abuse program for youth ages 13-17 who are struggling with drug or alcohol abuse. This teen substance abuse treatment program will take place at our young people’s counseling clinic in Phoenix, Arizona.
IOP may be recommended as teen drug treatment for those who do not need a medically-supervised detox. IOP group therapy can also enable teens in recovery to continue outpatient drug rehab following their successful detox, on a part-time, yet intensive, schedule, designed to accommodate school and family life.
In the Substance Use Disorder Intensive Outpatient Program, individuals receive teenage drug abuse treatment primarily through group therapy. Unlike the typical teenage drug treatment center, our groups are small and generally do not exceed 10 people, allowing for a safe and supportive environment for youth treatment.
Doorways has insurance contracts with Aetna, BCBS, Cigna and United Behavioral Healthcare for our IOP services. Please contact your insurance provider for coverage limits.
