In 1929, the then, Diocese of Galveston-Houston purchased six acres to start a new parish community in Southeast Texas. This new Church, located in Houston’s Riverside Terrace community, was named St. Mary of the Purification Catholic Church. The area surrounding the peaceful wooded church grounds would soon become home to St. Mary’s School. A temporary school building was erected in 1930 and opened September 8th with an enrollment of 35 pupils. The blessing of the old school building took place October 27, 1930. The Sisters of Dominic staffed the school until it closed in 1967. St. Mary’s school reopened in 1980 and adopted the Montessori System based on learning methods and styles developed by Dr. Maria Montessori. The school was recognized as the only African-American Montessori School in Texas.

On April 5, 1929, Monsignor M.J. Daly was appointed the first Pastor/Administrator of the school. He was followed by Father Dexter George in 1960. Father George was succeeded by Father Frederich O’Connor until 1968 when Father George Swilley became Pastor/Administrator in June 1968. In 1968, Father John LaBauve, SV.D. became the first African-American Pastor/Administrator. Father Charles Leisring, SV.D. replaced Father LaBauve in 1973. In 1975, Father George Artis, SV.D. became the Pastor/Administrator. It was under the leadership of Father Artis that the Montessori School, was opened in 1980.

Father Michael Fritzen, S.V.D. became the Pastor/Administrator in July 1996 until he was replaced by Father Francis Alvin Dixon in 1999. Father Dixon was replaced by Father F. Borgia Aubespin, S.V.D. in 2001. Father Aubespin was replaced in 2014 with Father Justin Arockiasamy, S.V.D., the current Pastor/Administrator.

Sister Edna Herbert, O.P. was the principal when the school was reopened in 1980. Mrs. Rose Ellis (the first lay principal of the school) succeeded Sister Herbert in 1985 and was principal from 1985 to 1994.
