Meet our Faculty

Sebastian Garren

Executive Director

Mr. Sebastian Garren has had the pleasure of teaching at JPII since 2015. He received a BA in Classical Languages and minors in Philosophy and Medieval Studies at Wabash College, was president of the Newman Center, was a Fulbright Scholar for Education in Finland, and is a Progress Fellow through Emergent Ventures at the Mercatus Center.

He is the founding director of St. John Paul II Preparatory South and teaches a broad range of classes to students, which are known for perfectly balancing delight with real learning.

An avid reader, he reads economics, folk tales, classics, poetry, and children’s books – really everything except 19th century French novels, which he has an irrational prejudice against.

5 things we love about JPII

JPII is first and foremost a community of Catholics striving together to live the Faith with confidence and joy.

JPII’s classical curriculum puts them in contact with the the greatest minds of Western Civilization and frees them to carry on the work of civilization and Christian culture. 

JPII’s teachers work closely with their parent co-teachers to ensure seamless application of our hybrid model; they challenge students with every step to analyze, compare, evaluate, and create.

JPII’s students are learn independence and self-efficacy through the hybrid model, and so are better equipped to grow in God’s grace and use their talents.

JPII’s close-knit “community of friends” works together with a level of courtesy, generosity, helpfulness, and kindness that is seldom experienced in organizations; people treat one another with a high degree of Christian charity and respect.

After studying at Thomas Aquinas College, Mr. Martel knew what he wanted to do with his life. The delight and wonder of learning were what he wanted to pass on to the younger generations. He has been involved with the home-schooling community here in St. Louis since the 1980’s and served as teacher at Gateway Academy and now currently at St. John Paul II. What Mr. Martel likes about JPII is its dedication to a classical curriculum as the best foundation for a solid education and its 3-day format allowing the parents to actively exercise their very important role of mentoring their children’s formation.

The Catholic faith also plays a central role in the presentation of all academic subjects integrating faith and reason so necessary for proper human development. All that he loved and was privileged to learn while at Thomas Aquinas College is what he wishes for all students of JPII.
