Founded in 1950, Mater Dei is more than a high school. We are a community built on fellowship and intellectual rigor, dedicated to developing our students' talents as they pursue their dreams of academic excellence, artistic distinction, athletic glory, and spiritual growth. Mater Dei and its students have influenced Orange County through campus ministry, the arts, academics and athletics.

Mater Dei students continue to become National Merit finalists, scientific scholars, CIF champions, award-winning artists and more! Our students are characterized by curiosity, ambition and service to others. Mater Dei students take these lessons with them as they move on to some of the most prestigious universities and well into their professional lives in the worlds of medicine, law, technology, finance, education, entertainment, government, business and ministry.

Whether you’re a student, parent, alumni or benefactor, know that Mater Dei is a place to call home. We are a family. WE ARE MD!
