Totus Tuus is a Catholic youth program for students from 1st through 12th grade dedicated to teaching the Gospel and deepening love for the Church through catechesis, prayer, Christian witness, and the sacraments.

The mission of Totus Tuus is to inspire in young people a true longing for holiness, a deep desire for daily conversion, and an openness to their vocation by challenging them to give themselves entirely to Christ through Mary and by strengthening their prayer lives in imitation of her.
