Welcome to the Home of the Cougars! We invite our alumni and current Cougars to keep up with all that’s happening at Gross Catholic, and prospective families to learn more about us. The Cougar Family is firmly rooted in our the Catholic faith, and we live by our motto: Dux Esto . . . Be a Leader!
Since 1968, Gross Catholic has emphasized the importance of excellence in academics, athletics, and service to others. We are proud to be a co-ed Archdiocesan Catholic high school guided by the Marianist tradition.
We are committed to serving and challenging every student with a rigorous college preparatory curriculum, while encouraging student involvement through activities, athletics, campus ministry, and apostolic outreach in our community.
Please feel free to contact us if you have any questions about our school or if we can be of assistance to you. God bless you.
