Chaminade Preparatory School educates young men, grades 6-12, in the Catholic Marianist tradition.

Chaminade's intention is to ensure that every young man that passes through our doors is able to achieve the balance between school life and play. Our school motto is ESTO VIR, "Be a Man" and reflects the journey from boyhood to manhood that includes spiritual, educational and social development.
