President & Principal's Message
Founded in 1950, Mater Dei is more than a high school. We are a community built on Catholic 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.
For over 67 years, 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, county-wide science fair winners, CIF champions, award-winning performers and artists and much 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.
Mater Dei High School recognizes the value of each and every student and his or her contribution to our traditions of Honor, Glory and Love which have been a part of the Monarch experience since our inception.
Whether you’re a prospective student or parent, alumnus, lifetime parent, current student or parent, or grandparent, know that Mater Dei is a place to call home. We are a family.
Thank you again for visiting our site and we look forward to the opportunity to see you in person on campus.
In Mary, Mater Dei,
Patrick Murphy, President Frances Clare, Principal
