History
The institution started as the Jesus’ Messianic Office of Teaching, founded in August 1996 as part of Manila Archdiocesan and Parochial Schools Association. The school was founded as a department of San Sebastian Parish in Pinagbuhatan, Pasig. It started to offer Early Childhood Education classes. It was renamed as Escuela Catolica de San Sebastian in 1998 and became the parochial school of the San Sebastian. In 2003, the Diocese of Pasig was established and an diocesan school system was formed that will supervise all catholic schools in Pasig, Pateros and Taguig. Through this, the school operated under the Pasig Catholic College. In 2004, it was recognized by the Department of Education.

The school started with only two teachers in the kinder level. As the school started to offer grade school classes, the school academic and professional staff grew. They were led by four school directors: Rev. Fr. David C. Colong, Rev. Fr. Ronnie M. Samaniego, Rev. Fr. Elpidio M. Geneta, and the incumbent Rev. Fr. Emmanuel C. Hipolito.
