Welcome to Duchesne High School.  We are a regional, Catholic high school (grades 9-12) of the Archdiocese of Saint Louis, Missouri, located in the eastern part of Saint Charles County.  Further, we are a co-educational, college preparatory school, dedicated to teaching the whole student: mind, body and spirit as one.  As a unique, faith-centered community, our instruction and activities

·         encourage intellectual development, critical thinking, and creativity;

·         nurture a personal relationship with God and an integration of faith and life;

·         promote a loving concern for others and service within the Church and the broader community;

·         encourage discovery of individual gifts and the development of healthy relationships; and

·         support and affirm the dignity of all persons within the school community and beyond. 

Although we are committed to a program of academic excellence, our broader goal is to inspire in our students a lifelong devotion to learning, a devotion that will serve them in making informed choices and in making a difference in the world.

We invite you to explore our new Web site, and better yet, come visit our campus; meet our students and faculty.  We’d like you to know this wonderful school.
