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 20, 2025

This week has been filled with gratitude and celebration with St. Philippine Duchesne’s Feast and Grandfriends Day. Mr. Timothy Horner, Head of School, reflects on her enduring vision — this community rooted in faith and love that continues to thrive — and the many blessings that sustain our mission.

At the conclusion of Philippine’s Feast Day Mass, I shared my belief that St. Philippine, from her place in heaven, looks upon her school as our foundress, smiling because she sees a community that has preserved its core for more than 200 years.

In this season of gratitude, I am thankful for:

  • The living of our Sacred Heart Charism and Catholic faith, which shape our community values and weave a rich tapestry of faith that underpins everything we do.
  • Our students, who foster a culture of kindness, faith, and warmth. Walking our halls, you see classmates helping one another and greeting you with a smile and a cheerful “good morning.”
  • Our remarkable faculty, whose deep care for students and unwavering dedication reflect their belief in each child’s potential.
  • Our supportive community, surrounding students and teachers with encouragement and resources.
  • The RSCJ, whose presence—whether at Board meetings, Masses, or in conversations with students and faculty—continues to bless us with grace and wisdom.
  • Our administration and staff, whose exceptional commitment ensures that, time and again, they rise to every occasion to do what is right for students and faculty.
  • Our volunteers, who quietly make events large and small possible—without whom our school simply could not thrive.

Together, these gifts create an extraordinary school. Thank you for your role in advancing our mission to reveal God’s love. As St. Philippine reminds us:

We cultivate a very small field for Christ. But we love it, knowing that God does not require great achievements, but a heart that holds back nothing for self.

May your Thanksgiving be filled with joy and surrounded by loved ones.
