About TRAK

The continued operation of TRAK is made possible by the organizations and individuals who want these important services available for the children and those in need throughout Tucson. TRAK could not accomplish this goal without the generous help of its many donors, volunteers, board of directors, and dedicated staff.

Executive Staff

Scott Tilley

Co-Founder and Executive Director

Scott was born and raised as a “city boy” in Scottsdale, AZ, spending his weekends fishing. At age ten, his family moved to a 20 acre ranch in New Mexico, where his closest neighbor was a race jockey and horse breeder. Scott spent every bit of his spare time with that neighbor, who became his mentor, teaching him all about horses: training, riding, breeding, farrier duties, all along with a strong work ethic. After high school, Scott worked for his father in their family tire shop and on the family cattle farm with livestock ranging from cattle to pigs, sheep and chickens. At age 30, Scott moved to Mexico and ran the Club Med horse program, while simultaneously running the Santosa Breeding Stables in Tucson. In 2007, TRAK was established by Scott with his wife, Jill.
Their three adult daughters spent their formative years enjoying all that TRAK has to offer. Scott’s hobbies are fishing and off-road racing.

Jazz Dolan

M.A. Therapy Team Lead , Equine Assisted Mental Health Specialist (EAGALA Certified)

Jazz has worked in the behavioral health field for the past 25 years, working in a variety of different settings with all age ranges from young toddlers to adults with both cognitive and mental health disorders.  She received her Bachelor of Science degree in Psychology with a minor in Spanish in 1997 and then taught English as a Second Language (ESL) for 2 years in Daegu, South Korea to elementary, middle school, and college level students before returning to the states to finish her graduate degree in Bilingual School Psychology in 2005 at the University of Arizona. Jazz worked full-time as a school psychologist from 2005-2017, most notably at Sonoran Schools where she was the Lead District School Psychologist for all 4 campuses in Tucson during a 6 year period. During this time, she was instrumental in writing 2 successful grants for the Department of Defense Education Activity (DoDEA) to help establish an evidence based social-emotional curriculum as well as STEM based math intervention program.

In addition, Jazz has a long history training with horses as a child and teen to include grooming, round penning, advanced riding, and jumping, while also participating in 4-H events & competitions. She is very excited to combine her love for horses with her passion for improving the lives of children and adolescents by helping them feel successful and capable, while at the same time decreasing any feelings of anxiety, depression, or low self-worth. Jazz was first introduced to animal therapy through Gabriel’s Angels while working for the Madison School District in Phoenix, Arizona and was very impressed with the power of animal therapy to break down barriers with students, allowing them to more fully express their desires and fears. This therapy showed great results with improving coping and social skills, verbal and non-verbal communication, and overall self-esteem and self-confidence. 

As the new AALS Program Developer, Jazz plans on utilizing her in depth clinical and therapeutic skills into developing an innovative experiential equine assisted therapy program that combines the EAGALA certification model with other forms of evidence based therapeutic modalities, depending on individual and group needs as well as clinician derived expertise. This program will be developed with support from the Program Director and Equine Specialist, Chelsea Menke. In addition, Jazz will use her grant writing experience to help research and write grants for future funding and looks forward to help strengthen kids and community through animal interactions.

Mandy Reitzell

Finance Manager

“I have been in the Finance field for 27 years, I have an AAS in Accounting and recently became certified as a Quickbooks Online Pro Advisor.  My passion is helping small businesses succeed and working with TRAK has allowed me to do just that.  Outside of work I am a busy mom that loves to travel.  A fun fact about me is math was always the subject I hated the most in school, yet here I am in finance.  It is hard for me to choose a favorite animal at TRAK but it is between Tinka and Jake the bunny”.
