On behalf of MHS faculty, staff, and administration, we welcome you to Nadaburg Unified School District's premiere high school! MHS has been a long time in the making and marks a significant milestone for our district and community. Our vision to reimagine and redefine a 21st-century education is achieved by 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 every student's academic, athletic, and student growth by giving them a voice and choice. Whether participating in-person or online, we understand our responsibility when choosing MHS to serve your student's educational needs. Our staff is committed to providing all students with the best learning experience possible.
