Administration


WELCOME TO MT. DIABLO HIGH SCHOOL

Greetings,
Mt. Diablo High School community, Hello, my name is Dr. Markell McCain, and I would like to introduce myself as the Principal of Mt. Diablo High School.
I look forward to serving our community and working with our most valuable asset: the students. I've been an educator for over twenty years,  first as a teacher for eight years and then as an administrator for twelve years, serving as both vice principal and principal. I'm excited about the opportunity to work with some outstanding teachers here at our school. My promise is that Mt. Diablo High School will be a place where students feel safe and respected and the campus is clean. I'm all about equity, inclusion, and student's voice-- these things are not negotiable. My expectation for students is that they come to school and attend class. My message to both students and teachers will be to form healthy relationships and figure out ways to communicate with each other respectfully. These things will be stressed by my administrative staff every day. I look forward to working with you and your child.
