Sharing the Promise…
Shaping the Future Campaign

We are proud to share that we are in the midst of a 40,000-square-foot renovation and expansion of the High School. 

The Sharing the Promise…Shaping the Future campaign is so important for our school and we are all excited about the areas that will be enhanced including science, fine arts, college counseling, admissions, and student life.

The Promise

The founding families of The Abbey of Saint Mary and Saint Louis and the founding monks from England made a promise to each other. 

One that stands today and one that will continue for generations to come.  The promise states that the monks would provide spiritual and educational guidance to the young men that passed through the school and the families would provide for all the earthly needs of the monastic community. This promise is the cornerstone of our success and the one that will continue to carry us forward.

This campaign and the projects it supports represents Priory’s commitment to our students and reflects our mission of educating young men both spiritually and intellectually. The renovation, expansion, and updated spaces will enhance how our students learn and continue our unique educational program well into the future.  Our success endures in the daily interactions and long-term relationships between the students and their teachers and spiritual mentors.
