About Us

“Run ahead of the herd” with the Mount Gleason Mustangs! Built in 1959, Mount Gleason Middle School, including the Gifted/High Ability Magnet and STEAM Magnet, is located in Sunland-Tujunga with a picturesque view of the San Gabriel Mountains. We have a dedicated staff committed to providing each student a rigorous standards-based program in a safe learning environment where students’ academic and social-emotional needs are met. Our effective library program, accessible modern technology, and capacity-building Parent Center support student achievement in literacy, numeracy, and beyond. Students appreciate our array of elective choices, extensive lunch club options, several after-school programs, popular annual traditions, and multiple forms of recognition. Upon culmination, the Mount Gleason family strives for all students to be college and career-ready young adults as well as compassionate human beings, creative thinkers, and self-directed lifelong learners. Go Mustangs!
