High School

Inspired by the writing of our patron, St. Thomas Aquinas, “To hand on to others the fruits of contemplation,” our academic program blends the practical with the profound. Our curriculum prepares students for college, but also equips them with a depth of knowledge to succeed in any field of study they choose. We believe truth is objective. We challenge our students to reflect on academic ideas and moral values worthy of contemplation, to engage in robust and free discussions, and to learn what is worth thinking about rather than what to think.

Faith and Reason

Faith and reason, working in harmony, form the foundation of our school. The theological virtues of faith, hope, and charity, as well as the cardinal virtues of prudence, justice, fortitude, and temperance inform the actions of our faculty and our students. Through our student-faculty advisory program and in every class, these core values are encouraged and developed in both our Catholic and non-Catholic students.

Human Connection and Community Engagement

Genuine human interaction without distraction from technology is essential for students to engage with one another and their teachers in a way that is no longer the norm. As soon as they arrive in the morning, our high school students turn in their phones, which fosters authentic conversations and meaningful connections. The hallways, lunchroom, and other extracurricular activities — clubs, athletics, drama productions, retreats and more — are enhanced by this deliberate tech-free choice. While students have access to laptops for papers, projects and computer courses, they read from physical books and take notes and complete tests and quizzes with paper and pencils, cultivating deeper focus and an engaged, active learning.

High School Curriculum

“What makes Aquinas different? Our faculty. Aquinas teachers not only have a deep understanding of our subjects, but a profound love for our students and a strong desire to share our knowledge.” Mrs. Sara Whetzel, Assistant High School School Director
