An apostolate vital to the Church and the world

Dedicated to our lady, seat of wisdom

Sedes Sapientiae means Seat of Wisdom

Under the patronage of Our Lady, Seat of Wisdom, we strive to endow our students with the love of learning that engenders wisdom in all aspects of life. Through our academic program, we prepare students not only for success in college, but to live lives consistent with what they learn. 

"But if any of you want wisdom, let him ask of God, who giveth to all men abundantly, and upbraideth not; and it shall be given him" (James 1:5)

Dedicated Educators

Sedes Sapientiae School faculty guide students in learning from the great thinkers

Our highly qualified faculty are committed to our mission of Classical Education. We call our teachers "tutors" because rather than just transfer information, they guide the students through the learning process in encountering and discussing the works of our primary teachers, the great writers and thinkers from Western and Catholic culture

Culture Formed by the Catholic Faith

Sedes Sapientiae School is faithful to the Catholic academic, theological, and spiritual heritage

Students and faculty begin each day with Morning Prayer or the Rosary, study Catholic theology, and learn other subjects from a Catholic perspective. Daily interactions are founded on Charity expressed as mutual respect, chastity, and courtesy.
