Sisters of the Congregation of the Incarnate Word and Blessed Sacrament from Houston, Texas, began at St. Mary's School in 1919 and had a presence in the school until the retirement in May 1995 of long-time librarian, Sister James Philip Davison.

Elementary students do have weekly music, band, Spanish, and technology classes.

Plans exist to expand the Reagan building even more, for the school is quickly running out of room.
