A Message from Principal Madrid

Dear Bulldogs,

Welcome to Sierra Linda High School’s website! The 2019-2020 school year promises to be another exciting year in the Bulldog Nation! Throughout the year, everyone will continue to focus on being Professional, taking Action, Working together, and being Safe.

We will be creating many new memories through our academic programs, classroom activities, clubs, sports, and co-extracurricular opportunities. We also welcome the addition of our new performing and fine arts center (PAC), located near the south entrance of the school (near the gym). We are truly excited about the PAC! I want to thank our parents and school community for supporting the project through their yes vote during the last district bond election. The PAC’s scheduled opening is in early April of this school year. This means our seniors may be the first senior class to perform in the PAC!

In closing, I want to thank everyone in advance for their support of our school, the school community, and the Tolleson Union High School District. As always, we encourage everyone to keep informed. Please visit our comprehensive website calendar, Peachjar, Dawgpound Media, Facebook, Twitter, Instagram, and ParentVue sites. Have a fantastic and productive school year Bulldogs and never forget to Dream, Believe, Strive, and Achieve!
