PARENT FEEDBACK:  Many examples of Parent Feedback are posted on our ASAP website. Here is just one recent example, from parent P.P. in 2023:


As a parent, it takes a lot to admit that you need help for your child. When I finally came to this conclusion I learned about the ASAP program through it was truly a blessing for my family. Our child received the best possible care during his time in the ASAP program from all of the licensed staff. Therapy was three days per week, three hour sessions. Monday night was Family night and I was able to attend each Monday session with my child. I could go on-and-on about the staff, they are truly the best and I couldn't have asked for a better experience. As a parent observing other children as well, it was such an inclusive and collaborative experience for all- It was great to see teenagers overcome their addictions during this program and begin to see a better (sober) life. When you graduate from the program, ASAP provides you with a list of recommendations and will also meet with parents and teens to discuss next steps. They have a vast network of trusted partners in the community and are there for you every step of the way. I have also had many direct conversations with the program Director Dr. Walling and he has been a great resource for the struggles that we have had achieving sobriety. Lastly, I would just like to say THANK YOU to the therapy staff,  Letron, Diana, Itati, Jessie, and Paul.




Arizona's Best Teen Drug Treatment                                     

phone open Mon-Fri,  9am to 9pm


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 long 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.  Drug testing is utilized as a critical tool to verify that teens are no longer using addictive substances. 

Please be advised that ASAP is specialty facility.  ASAP is an Intensive Outpatient Program (IOP) facility for counseling only, we are not an inpatient facility, or a residential treatment facility, or a detox facility.


In 2024 ASAP proudly celebrated its 33rd year.  All ASAP programming is based on evidence-based, "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 -- we invite the reader to click on the "Free Resources" page to view more than 100 powerful testimonials hand-written by former ASAP parents and teens.

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 drug testing.  An eclectic treatment model and a diverse staff are utilized to approach adolescents from many 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 the ASAP Teen and Parent Homework handouts are utilized for growth-oriented homework assignments.  Parents are taught techniques for 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 evidence-based and follows "best practices".  No smoking is ever allowed at ASAP, and strict adherence to the highest ethical standards is maintained.  You will find our ASAP website easy to use-- we believe the simplest website is best.  ASAP is proudly committed to changing the lives of teens and families!

ASAP contracts with all major private health insurance companies, including Aetna, Blue Cross/Blue Shield, Cigna, United (Optum), Ambetter (MHN), HealthNet, Humana, Magellan, Beacon, ComPsych, Multiplan, AZ Foundation, Mines and Associates, Meritain, HMC, Value Options, AmeriBen, Coventry/First Health, and many more.  ASAP is also contracted with the following AHCCCS Plans:  United, Health Choice, Banner University, Arizona Complete Health, and Molina.  For more information, please call (602) 434-0249.
