A Legacy of Faith Since 1877

For nearly 150 years, St. Mary's Catholic School has partnered with families to provide an education rooted in faith, academic excellence, and service. As the oldest Catholic elementary school in the Diocese of Dallas, our history continues to shape generations of students and leaders.

Our Beginnings

St. Mary's Catholic School was founded in 1877 by the Sisters of St. Mary of Namur, who came to Sherman with a mission to provide Catholic education to local children. Originally known as St. Joseph's Academy, the school quickly became a cornerstone of both the parish and the surrounding community.

Growing With Our Community

For generations, St. Mary's has educated the whole child—mind, body, and spirit. While our campus, programs, and classrooms have evolved over time, our commitment to forming students in faith, character, and academic excellence has remained unchanged.

Today, our teachers continue the legacy established by the Sisters of St. Mary of Namur, inspiring students to lead lives of purpose, compassion, and service.
