It was sometime in 2000 that the Magbitang couple, Jorge and Adelaida conceived of establishing a school in their vacant lot at Quijano St, San Juan, San Ildefonso, Bulacan. It was their way of giving back to the community for the many blessings they have received from the Lord Almighty. Together, with the support of their close relatives, particularly the family of Ma’am Adelaida, the dream became a reality. MONTESSORI DE SAN ILDEFONSO (MDSI, for brevity) started its operations in June 2002. To prepare themselves to manage the school effectively, Mrs. Magbitang took specialized courses and trainings on Montessori education.
MDSI is now a growing private, non-sectarian educational institution in Bulacan. It is situated in a two (2) hectare spacious lot. The campus is surrounded by concrete fence and with four (4) steel gates for entrances and exits. The safety and security of the students and the employees is of utmost concern to the school management.
