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


October 16, 2025

As we approach the Feast of Mater Admirabilis on Monday, Amaya Firestone, Marketing and Communications Assistant, considers what Mater can teach us in today’s fast-paced, ever changing world.

Reflecting on the virtues of Mater Admirabilis is a daily joy for me here at the Academy, and writing this week in anticipation of her feast day fills me with gratitude for this special Sacred Heart tradition. On October 20, the global Sacred Heart family journeys back in time to 1844, when young postulant Pauline Perdrau set brush to wall and brought to life a visage of Mary not often contemplated — an adolescent, full of grace and interior silence, but waiting for her mission. Her surroundings are fresh, open, and airy. Her hands are busy with spindle and distaff and a book. She wears a rosy pink gown.

This unique Mary has been claimed as the patron saint of Sacred Heart students. I find her graces to be immensely accessible and applicable in the modern digital age, and I am grateful she is taking special care of our students, which include my three boys, Lucas, Warren, and Peter.
