WelcomeTres Rios Service Learning Academy

Welcome to Tres Rios Service Academy, home of the Pumas! We are a K- 8 school in the Littleton Elementary School District #65. Located in Tolleson, Arizona, approximately 18 miles west of downtown Phoenix, we enjoy a friendly, family-oriented, small town atmosphere.

At Tres Rios we believe in the development of learning communities, and that every child can and will learn if provided an appropriate environment. We are committed to providing the tools to help our students be healthy, successful, lifelong learners. We offer a variety of programs to meet the needs and interests of our students, including an athletics program, special education, a band program and gifted program, as well as state-of-the-art technology.

We recognize the value and importance of parent/guardian participation in a child’s education and welcome your involvement. We have provided several ways to help you stay connected, including a Facebook page, Twitter, and this website. We thank you for your interest in our school and for supporting your child(ren), as we work together to educate and prepare our most precious assets, our children, to take on the world!

Thank you now enrolling

A Message from our Principal

Tres Rios Families,

Welcome back! Happy New Year, new school year that is. I hope that you were able to relax, refuel, and enjoy the summer. We have wonderful things in store for our students this year. We have added some fabulous new teachers to our staff. They are looking forward to the upcoming school year and working with you and your students. Our administrative team welcomes back Mr. Blanton as our assistant principal, and we welcome Ms. Westberg as our dean of students.
