Hyde Park

In 1892, the Congregation arrived in the United States when four Sisters of Sion began educating young children in Auburn and Lewiston, Maine. By 1904, the number of Sisters had grown to sixty. In 1907, the Sisters transferred to Marshall, Missouri, where they taught at Sion Academy until 1925. In 1912, Bishop Thomas Francis Lillis invited seven Sisters to Kansas City. Two taught in the Annunciation School. The others began a French kindergarten and gave private sewing, music, and French lessons, which grew into the Notre Dame de Sion School. For decades to follow, the Sisters continued managing and growing the institution, building their first campus in Kansas City's historic Hyde Park.

In 1953, Bobby Greenlease was kidnapped from the Hyde Park school by a woman claiming to be his aunt. The $600,000 ransom paid by his family was the largest paid to that point, although Greenlease had been killed before the ransom was paid.^[2]

The original campus is now Notre Dame de Sion Grade School for Girls and Boys and located at 3823 Locust and the structure was finished in 1927. The college preparatory institution is co-ed and includes four divisions: Early Childhood (PreK Montessori that teaches children from ages two through four or five), Primary (kindergarten through third grade), Intermediate (fourth and fifth grades), and Middle (sixth, seventh, and eighth grades). The campus features many prayer paths and student working in Maisons and Faith Families complete various service projects aligned with the Corporal Works of Mercy.

South Kansas City

In 1962, the high school moved to South Kansas City at 10631 Wornall Rd. Six years later the Sisters invited lay members to serve on the school's board of trustees, and in 1990 the ownership of the school was transferred to the Board.
