Gilroy Catholic College is a Parramatta Diocesan Year 7 to 12 co-educational High School.
The school was established in 1980 by parents who saw the need for the school in the Hills district.
Gilroy Catholic College seeks to deepen students' faith in Jesus Christ through study, prayer, worship, sacramental life and service so that the College motto "Christ is my Light" is truly lived. The College acknowledges the role of parents as first and foremost educators of their children and the role of the pastors in the faith formation of students. Hence, links with the local parishes are vital in the life of the College.
The quality of relationships is based firmly in the Gospel belief of the uniqueness and dignity of each person. In this environment students are free to fully develop their potential and to experience the challenges of learning, growing and reaching out to others in a Christian community.
