The Adolescent Substance Abuse Program (ASAP) has proven itself Arizona's finest treatment program for young people involved with alcohol and drugs since 1991. 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 intensive outpatient program (IOP) 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 adolescents and their families to reestablish a sober, safe, and mutually supportive relationship.

Active participation is required of both adolescents and their parents. Interventions include 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 took at all sites, and many ASAP handouts are utilized for growth-oriented homework assignments. Parents are taught the best 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. No smoking is allowed in ASAP facilities. Strict adherence to the highest ethical standards is maintained.

ASAP contracts with all major private health insurance companies (the one exception is TriCare). ASAP is not an AHCCCS Provider, ASAP is not contracted with AHCCCS. For admission, or for more information, call (602)434-0249.
