Mater Dei is a distinguished destination of excellence in academics and technology, the arts, faith and service, campus life, and athletics. We are proud to be Orange County’s oldest and largest Catholic high school.
Your journey to becoming a Monarch starts here! Tour campus, schedule a shadow day, begin your application, and more. We are excited for you to join the MD family!
Built on Catholic fellowship and intellectual rigor, our programs in academics, technology, athletics, faith and service, and the arts provide unlimited opportunities for student success. Comprehensive counseling and wellness resources educate and bolster families throughout the high school journey.
Through avenues of leadership, faith, shared interests, and extracurricular activities and events, students can make Mater Dei their own. Get involved today!
Tradition never graduates. Alumni, lifetime parents, grandparents, and friends are a vital and vibrant aspect of our community. Once a Monarch, always a Monarch.
Behind every achievement, success, and championship, stand the alumni, parents, faculty, staff, and friends who fortify our future. We invite you to support MD in a variety of ways with a gift that is meaningful to you.
