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


February 12, 2026

At February’s Board of Trustees meeting, Miss Hannah Haguewood, First Class teacher, and Mrs. Elizabeth Johnson, Fifth and Sixth Class language arts teacher, presented about their experience at the Academy. Both are in their second year at the Academy and share how it has impacted them as educators.

After applying for the position of Seventh and Eighth Class language arts teacher and being interviewed, I was asked to shadow the Middle School for a day. When I walked onto campus for the first time, I was amazed by the respect and happiness that emanated from the students and faculty. I was coming from a school without any religious affiliation, but coming to the Academy, I could feel a joy in the atmosphere that can only be felt through God’s doing.

My first year teaching at the Academy was a year where God blessed me with working with wonderful teachers and Seventh and Eighth Class students. I loved how each child understood their responsibility to serve others, own up to their mistakes, and value their education. That is rare to find in schools these days. I will cherish not only the lessons I taught to the students last year, but the lessons I learned from them.

Toward the end of last year, I was given the opportunity to teach an additional First Class this current year. Putting my faith in the journey God has for me, I said yes to that opportunity. It has been eye opening to see ASH from an elementary perspective. Again, the students that make up the ASH family are one-of-a-kind, and the teachers that are working alongside of me have been very helpful in assisting me. I will say, working with the little ones definitely requires an extra cup of coffee in the morning!

The Academy of the Sacred Heart has made me love teaching again, and I am grateful to both God and St. Rose Philippine Duchesne for guiding me along this path.
