About the School

We, the faculty and staff of St. Louise de Marillac Parish School, strive to assist parents in their role as primary educators seeking to prepare children to proclaim the Good News imparted by the Gospel of Jesus Christ.
We foster academic excellence while recognizing each student's unique abilities toward achieving age-appropriate mastery through an integrated curriculum.
Our goal is to see that the children of St. Louise grow in fellowship as persons of faith and charity, enabling them to take part in the church's mission to the world through service.
St. Louise de Marillac School is a parish school that strives to maintain the rich Catholic tradition imparted by the Gospel of Jesus Christ through an integrated curriculum.
In order to maintain this tradition, the clergy, faculty, and students are united and continually renewed by the gospel, which is transmitted through community and expressed in service.
This expression of unity is primarily found in the celebration of the Sunday Eucharist that binds each of us together.

School Reviews

5 5/17/2016

My children currently attend St. Louise, and we are very satisfied with the education they are receiving. It is a small, private school, with a strong family atmosphere. Parents are extremely involved, and are provided with many opportunities to become so. The school strives to be academically competitive, is currently investing in their technology program, and offers numerous extra curricular activities. You won't find a better school in the area!
