About Us

Marin Catholic is an Archdiocesan, Catholic, co-ed college prep high school founded on the values of faith, knowledge, and service. The young men and women attending Marin Catholic are dedicated, accomplished students, willing and able to undertake the challenges of a college preparatory program and make their unique contribution to the school community. Our school motto, Duc in Altum, comes from Chapter 5 of Luke's Gospel when Jesus asks Peter to "cast your nets out into the deep."  We hope each student learns to trust in the Lord, goes out into the deep--spiritually, academically, artistically, athletically--and in return has their nets filled.
