The founder's dream of putting up a Catholic co-educational institution in the parish was made a reality by the generosity of the Daet Parishioners and the moral and financial support extended by Msgr.

From then on, the Family Council (FC), an organization of parents and teachers of the school, and the Board of Trustees had been made functional.

Four Catalan Augustinian Sisters arrived in Manila from the port of Barcelona, Spain, on April 6, 1883, to dedicate themselves to care for and educate the orphans of the 1882 cholera epidemic by establishing the Asilo-Colegio de Manadaloya.

In 1899, these Filipino Sisters took possession of the Franciscan buildings in Sampaloc and opened an asilo-colegio just in time for the start of classes in June.

In 1902, through the beseeching of the clergy, the orphanage-school became a full-pledge academic institution whose objective was to provide training to those intending to pass the civil service exam that the students might be able to teach in the public schools.

Antonino O. Reganit busied himself with the reconstruction of the damaged convent which he promised to convert into a parochial school.

Upon the request of Bishop Pedro Santos, D.D., the Augustinian Sisters of the Philippines agreed to manage the school beginning SY 1949–1950 with Sor.

The legacy brought by the Augustinian Sisters and the pioneer teachers were carried on until the first High School graduation on April 15 of 1953.
