Jack Ryan will bring his love for Latin and history to the students at Chesterton Academy of St. Louis. Jack graduated from Saint Louis University in 2023 with a Bachelor of Arts in Philosophy, Catholic Studies, Classical Humanities, and Greek & Latin Language and Literature. He has a strong work ethic and a zeal for excellence in his work, which he gained, in part, from his years in the Boy Scouts.

There, he studied moral and Trinitarian theology, philosophy, and medieval and Renaissance Italian history. Additionally, Jack has taught catechesis to eighth-grade confirmandi at St. Clare of Assisi Catholic School and served as a teacher's assistant, tutor, and substitute teacher for introductory Latin at Saint Louis University.

Gregory and Augustine, he serves the Extraordinary Form of the Roman Rite, further enhancing his knowledge of Latin and Catholic traditions. With his broad scope of knowledge and passion for teaching, Jack is committed to passing on the treasures he has learned to his students at Chesterton Academy.
