The congregation of the Caritas Sisters of Jesus was founded by Italian priests belonging to the Salesians of Don Bosco in 1937 in Miyazaki, Japan. The founder, Fr. Antonio Cavoli, SDB named the congregation "Caritas" because it started with the love and concern for the poor people. The love and self-sacrificing work of the Caritas sisters for the abandoned won the hearts of many non-Catholics and led them to God, and helped spread the Caritas sisters missionary presence in 11 countries with around 500 Japanese sisters and 500 Koreans. It was in 1992 that the first work offered to them was to set up a school in response to the growing needs of the new community in Laguna Technopark. The Salesian community offered them the parcel of land situated at the junction of Sta. Rosa and Biñan, Laguna. Since the donated land was still bare, the homeowners of Sta. Rosa Village, a village within the vicinity, offered their Multi-Purpose Hall to be the temporary learning site. As a result, a co-educational school was established in 1994. CDBS had a humble beginning consisting of 21 pre-schoolers and three Caritas sisters together with two lay teachers. Today, the CDBS family has grown with more than 1,000 in student population and more than a hundred faculty and staff. They now have eight buildings and a chapel named Stella Maris.
