Message From The Principal

Spartan Families,

Welcome to the start of another exciting school year at Rio Mesa High School! As we prepare to begin classes on Wednesday, August 13, our entire team is energized and ready to support our students in reaching their full potential. The first day of school is always filled with anticipation and possibility, and we are committed to creating a positive, engaging, and safe environment where every student can learn and thrive.

This year, we look forward to building on our strong traditions while embracing new opportunities for growth and innovation. From our academic programs to our extracurricular activities, we are dedicated to providing a well rounded experience that challenges and inspires our students. We encourage families to stay connected and engaged throughout the year. Your partnership is key to our collective success.

Thank you for entrusting us with your child’s education. We can’t wait to see our Spartans back on campus, ready to learn, grow, and make this year one to remember!
