Faithful to God, whose name graces our school, Holy Trinity Catholic School strives to embody a community of the faithful joined intimately with Christ, the incarnate revelation of the Father, through the unifying love of the Holy Spirit.
The parish communities of Fairview Heights, Caseyville, and the surrounding areas, in communion with the Devine persons, are committed to education children and forming disciples of Christ through the disciplines of academic excellence, prayer, spiritual and moral formation, apostolic action, social awareness, and responsibility.
It is our mission to empower parents, the primary educators of our children, in their role of passing on the lifelong values and traditions of the Roman Catholic faith.
In the compassionate spirit of the Holy Trinity, our vision is an innovative, challenging, high quality Catholic education that creates a powerful parish community, which inspires our children to realize their individual dreams fostering a life-long commitment to learning.
