Dear Cowboy Families,

I am so honored to be the principal of Riverdale High School. Riverdale Joint Unified School District has been my family for the past 22 years. First as a U.S. History teacher, then Assistant Principal and now as Principal. I love working with our amazing students, staff and families.

“Equitable, empowering education for all”

At RHS our goal is to provide all of our students with opportunities that best support their futures after graduation. We are dedicated to helping students build confidence within themselves to reach their full potential. We strive to provide access to the opportunities necessary to support their future goals of attending a 2 or 4 year college or university, vocational or technical school, or employment in the workforce after graduation.

We encourage our students, as well as families to participate in RHS events including athletic, club, and extracurricular opportunities so they can be connected to each other and provide valuable leadership to our school.

Our administrative, teaching, and support teams look forward to walking alongside your student while at Riverdale High School and helping them to find their best future path

Have a wonderful 2025-2026 school year and GO COWBOYS!

Mrs. Stasha Tiller

Principal
