Why the Academy?

The Academy of the Sacred Heart is an independent Catholic school in St. Charles, Missouri open to 3-year-old through 8th grade children of all faiths. Our program offers students the opportunity to learn and grow in a safe and happy environment, with a focus on building strong academic skills while fostering independent learning and communication. Curriculum highlights include: two Science labs, a Makerspace, 1:1 computing, French and Spanish, daily Physical Education, and recognized art, music and athletic programs.

Founded in 1818 by St. Philippine Duchesne, the Academy was the first of many Sacred Heart schools established in the United States. Our mission is to educate and inspire the heart and mind of each child to become a courageous and confident leader who knows and loves God, and who reveals that love by serving others. Our graduates are young men and women well prepared for the challenges of high school, college, and beyond.

From the Heart


November 6, 2025

This week, Maureen Glavin, RSCJ returned to campus to spend time with students. Sister Glavin made her first vows as a Religious of the Sacred Heart in the Shrine of St. Philippine Duchesne and taught Seventh Class math and science for four years. In 2004, she returned to the Academy as Head of School until 2017. She then served on the Provincial Team (the leadership team for the Society of the Sacred Heart — United States and Canada). Last summer, Sister Glavin returned to the U.S. after serving in Indonesia and is again a member of the Provincial Team. Below, she shares about her time with Academy students this week.

On Monday I had the joy of attending the Third Class Little Glimpses and the All Saints Day Mass. Subsequent to Mass I met the Seventh and Eighth Class students for a short assembly. On Wednesday I met with the Third and Fourth Class students for their assembly and tomorrow I will be meeting with Fifth and Sixth Class students. What is abundantly clear to me is that the current administration, adroitly led by Mr. Horner and Mrs. Reepmeyer, are doing a marvelous job creating the space in which faculty, staff, and students are living the essence of Sacred Heart education by nurturing an authentic relationship with and understanding of Love’s Very Self (i.e. God), fostering an engaging learning environment, and encouraging choices and actions which reflect God’s Spirit.
