You can trust that the essentials for academic advancement and faith formation are met. Because when it comes to teaching children important foundations, experience matters.

Catholic Identity 

The importance of Catholic identity is critical in today’s formation in the Catholic faith and the future of the church.

  • As part of our commitment to spiritual professional development, a new course has been introduced focused on educators and on understanding and cultivating Catholic identity
  • A specialized professional development course on the Theology of the Body recognizes the need for a comprehensive understanding of the Catholic perspective on dignity, human anthropology, and God’s plan at different stages of life.
