Programs
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.
Faith in Action
Guided by the articulation of Catholic Social Teachings, Mater Dei prioritizes the faith development of our students with an emphasis on Christian service. We believe this allows our students to grow in their spiritual lives while living our gospel values through giving back to others and truly experiencing the face of God.
Campus Life
Through avenues of leadership, faith, shared interests, and extracurricular activities and events, students can make Mater Dei their own. Get involved today!
Community
Tradition never graduates. Alumni, lifetime parents, grandparents, and friends are a vital and vibrant aspect of our community. Once a Monarch, always a Monarch.
