The Adolescent Substance Abuse Program

  NOTE:  The ASAP Program is now online

The Adolescent Substance Abuse Program (commonly known as "ASAP") has proudly proven itself Arizona's finest outpatient counseling program for young people ages 12-18 involved with drugs and alcohol since 1991. 

ASAP is a 10-week Intensive Outpatient Program (IOP) designed specifically for the treatment of substance use disorders in youth ages 12-18.  Group therapy is the primary treatment modality  -- group therapy has proven the most effective technique with teen substance use.  At ASAP the teens attend group therapy three nights per week for 10 weeks, for a total of 30 group therapy sessions, and their parents also get help when they attend one of those sessions each week with their teen, at Parent Night.  Urine drug testing is utilized as a critical tool to verify that teens are no longer using addictive substances. 


In 2020 ASAP will proudly celebrate its 29th year.  All ASAP programming is based on research proven, "best practices" interventions.  Designed by three Phoenix-area psychologists, Dr. Phil Lett, Dr. Mark Rohde and Dr. Curtis Walling, the ASAP IOP Program pursues the "real-world" changes in home, family, peer, and school environments that yield lasting sobriety and a vastly improved quality of life for the entire family.  The goal of the ASAP IOP Program is to help teens and families re-establish a sober, safe, and mutually supportive relationship.  At ASAP we are proud of our long history of treatment success with teens-- we invite the reader to click on the "Free Resources" page to view more than 100 powerful testimonials hand-written by former ASAP parents.

In the ASAP program active participation is required of both adolescents and their parents.  Treatment includes comprehensive admission evaluation, drug education, coping skills training, emotional processing, group therapy, multifamily therapy, and urine drug testing.  An eclectic treatment model and an eclectic staff are utilized to approach adolescents from many diverse angles.  The ASAP Handbook and FAQ's orient adolescents and their parents to the ASAP program.  The ASAP Curriculum is utilized as an effective teaching tool at all sites, and ASAP handouts are utilized for growth-oriented homework assignments.  Parents are taught techniques for urine drug testing at home that can serve as the best deterrent of ongoing drug use.  Outcome studies and satisfaction surveys are conducted to measure treatment success and provide the feedback necessary for continuous quality improvement.  All ASAP treatment is research-based and follows "best practices".  No smoking is never allowed in ASAP facilities, and strict adherence to the highest ethical standards is maintained.  You will find our website easy to use-- we believe the simplest website is best.  ASAP is proudly committed to changing the lives of teens and families!
