Advancement Team

St. Thomas Aquinas High School is committed to ensuring that the Lux In Tenebris tradition- in both form and function- continues for generations to come.

Donors to St. Thomas Aquinas give for many reasons and their generosity has an immense impact on the STA community. Our charge is to be good stewards of all donations and contributions, both financial and in-kind, such that our school community can continue to empower its students to grow as learners and leaders.
