LCS reflects the diverse and unique flavor of its bicultural surroundings. The school traces its roots to Sacred Heart School, a parochial school. In 1934, the Minim Daughters of Mary Immaculate were asked to administer Sacred Heart School. From the beginning, the school exemplified a definite missionary spirit, with the Sisters organizing several catechetical centers in the city, as well as the outlying communities of Patagonia, Tubac, Carmen, and others. The Minims also established Our Lady of Lourdes Academy in 1940, where grades 4, 5, and 6 of Sacred Heart School were transferred to better meet the needs of the local communities. This marked the beginning of an intertwined history of the two sister schools. Grades were moved between both campuses as the needs dictated.
