Mount Aviat Academy has its roots in French soil where the Oblate Sisters of St. Francis de Sales were founded by Fr. Louis Brisson and our namesake, St. Leonie Aviat.


The Oblate Sisters of St. Francis de Sales set Mount Aviat Academy apart from other schools. With their very lives, our Sisters witness to God's faithfulness and inspire us to be all that God wants us to be. Our school resonates with the teachings and charism of St. Francis de Sales: an awareness of God's presence throughout our school-day and a deep respect for one another as God's children.

An order that would grow to serve in four continents and nine countries throughout the world, the Oblate Sisters of Francis de Sales were founded in 1866 by Fr. Louis Brisson and St. Leonie Aviat in Troyes, France. Their work originally centered on the young women who flocked to big cities during the Industrial Revolution looking for employment. Separated from their families, these young women had physical as well as spiritual needs. The Oblate Sisters followed God's call and sought to meet those needs.

From Troyes, France, our Sisters spread throughout Europe, to Africa, Latin America and finally, the United States. Our Sisters operate missions, schools, orphanages and retirement homes all over the globe. They teach in parish religious education programs, visit the sick and elderly, and minister to the poor. Today you can find Oblate Sisters in France, Switzerland, Austria, Germany, Italy, Namibia, South Africa, Ecuador, Colombia and the United States - but most importantly to us, in Childs, Maryland. Wherever the Oblate Sisters of St. Francis de Sales work and live, they strive to Live Jesus and to draw souls closer to him in love
