Loreto Day School was founded on the 10th of January 1956 by S.M. Gertrude O'Keefe. This School is a Catholic Institution under the management of the Sisters of the Institute of The Blessed Virgin Mary (Loreto Sisters), which was founded by Mary Ward in the 17th century, who recognized the significance of education for women and the important role they play in society.

In 1821, Teresa Ball established the first House of the Institute in Ireland and called it Loreto, the name by which all the subsequent foundations made from Ireland are still known. In 1841, Loreto Sisters under the leadership of Delphine Hart came to India. The religious Order is now spread throughout the world and engages itself in many fields, including the education of girls
