Operation Brotherhood Montessori Center Incorporated (sometimes known as OB Montessori Center Inc. or OBMCI) is an Italian-based school in the Philippines named after Maria Montessori. It was founded by Preciosa Soliven.[1] The mother organization Operation Brotherhood International was founded by Oscar B. Arellano. OBI provided medical help and community upliftment assistance to the war refugees in Vietnam and Laos. When OBI started operations in the Philippines in 1963, village projects became its first priority including schools for the poor. Ambassador Preciosa S. Soliven who had been teaching young children in Vietnam and later worked with a Swiss Montessori preschool teacher in Makati was asked by OBI to manage these schools.[2] OB Montessori offers toddler, pre-school (known as Casa), elementary school, high school and college levels and is the first school in the Philippines to use the Montessori method.[3]
The school offers subjects that are rare in other schools, such as agriculture, botany, zoology, wildlife research, home arts/technology and livelihood education, law on persons, accounting, values education and leadership training. Geometry can be studied by students starting from CASA (pre-school). However, it is understood that these subjects are not looked upon in the university level.
