In the spring of 1919, a two room school was built and in September, 1919, with sixty pupils and two Sisters of St. Mary’s in charge, the school opened. Two years later, two classrooms were added and later more property was acquired and an auditorium/gymnasium, more classrooms, and an athletic field were added. This completed the parish unit of church, rectory, convent, and school. Twelve classrooms with twelve teachers afforded complete facilities for not only the grammar school, but also a four-year standardized and accredited high school course for boys and girls.

In the 1940’s, the high school closed and the school returned to serving grades one through eight. In the late 50’s and early 60’s, the school reached its peak enrollment of 800 students.

In 1953, a new brick wing with five new classrooms, restrooms, health room, and basement storage area was built. Another three classrooms, library, office, faculty room, restrooms, and a storage area were added about ten years later. In 1973, construction was begun on a parish center. At the close of the 73-74 school year, the original wooden school building was demolished and the present facility was completed with the addition of a new gymnasium and library. The cafeteria was relocated in the new parish center. In 1987-1988, a kindergarten was added in a remodeled area of the parish center. Since then, several remodeling projects have been undertaken, including the addition of a computer room and a music room.
