Empowering student voice to create opportunity and options for every student, every day, by revealing talent and greatness within every individual

Welcome Class of 2025

Welcome to Mountainside High School

On behalf of MHS faculty, staff, and administration, we welcome you to Nadaburg Unified School District's premiere high school! MHS has been a longtime in the making and marks an important milestone for our district and community.  Though our inaugural year has been confronted with the challenge of educating during a global pandemic, it has also been an opportunity to reimagine and redefine a 21st century education, keeping what's best for students front and center.  We do so by leveraging technology for more than just efficiency.  We leverage our technologies to meet students' individual learning needs and to increase critical thinking and relevant real-world applications.  Our goal is to provide as many opportunities as possible for academic, athletic, and student growth for every student by listening to our students.  Whether participating online or in-person learning, we understand the responsibility entrusted to us when choosing MHS to serve your student's educational needs.  Though we face unique challenges due to COVID-19, our staff is committed to providing the best learning experience possible.
