What Boys Want

What Boys Need

Our universal Jesuit profile of the Graduate at Graduation means we are equally committed to our students’ academic success as we are to forming well-rounded humans with their eyes toward deepening a relationship with God.

We are strengthened by a network of nearly 90 Jesuit secondary schools in the US.

Our philosophy of cura personalis (care for the individual) drives genuine relationships and care for each individual student.

Our comprehensive service programs instill a lifetime habit of service and encourage students at each grade level to be men for and with others.

We help students become loving and faith-filled human beings through retreats, daily prayer, reflection, service, senior compañeros program, athletics, and community celebrations.
