A fervent commitment to help provide quality but affordable education to children of AFP personnel is the very essence of the existence of Integrated Montessori Center. Mrs. Angeli C. Cadungog, now called Teacher Angie, the founder-directress of IMC is a General Nurse graduate. She was trained in the Montessori system of education under the strict guidance of Mrs. Preciosa S. Soliven, the founder-directress of O.B. Montessori. After 10 years of teaching service at O.B. Montessori and 2 years at the International Center for Beginning Beginners (ICBB) located inside Dasmariñas Village, Makati City, Teacher Angie put up Integrated Montessori Center (IMC) in 1992. Inspired and committed to serve the needs of the AFP community in education, she asked permission from then CG, PA, Brig. Gen Arturo T. Enrile to convert a portion of the government quarters assigned to her husband into a classroom. DECS (Department of Education, Culture and Sports) issued a government permit to operate the school in 1994 and was subsequently recognized in 1995.
Since 1992, IMC has continued to grow and remained steadfast in its commitment to provide quality education. Due to popular demand, considering cost cutting on school transportation services and safety of the students, Preschool branches were put up in the areas of Villamor Air Base, Pasay City; Guadalupe Nuevo, Makati City; and Halang, Calamba City, Laguna.
The parents again appealed to Teacher Angie to establish a Grade School in 1997 because they wanted their children to continue their studies at IMC. Teacher Angie was challenged once more and looked for a place to construct the Grade School building. By God's grace, her prayers were answered when a lot at AFPOVAI, Bayani Road, Fort Bonifacio Taguig was available for this purpose. A four-storey building was constructed to accommodate Grades One to Six pupils in school year 2000. The elementary department in this area was granted Government Recognition by DepEd-NCR on January 23, 2002. The elementary school department has consistently progressed through the able leadership of its Principal, Mrs. Myrna Y. Benito.
IMC added another milestone to its educational ladder when its High School Department was opened in school year 2001-2002, due to the insistence of parents and encouragement of the Department of Education officials. Dr. Eden A. Cabulay, former DepEd-NCR-Division Supervisor of Makati City joined IMC to share her expertise in education. She has introduced innovative programs to enrich the curriculum especially in the high school department in which she was the Principal. The High School department was given its Government Recognition by DepEd-NCR on April 7, 2006.
For more than 30 years, IMC has bravely faced the challenges brought about by science, technology and social changes. With the concerted efforts of its strong teaching force, dynamic school administrators, and very supportive school board officials, the school has leaped frog in its development, upholding its battle cry: "ONWARD TO EXCELLENCE." The students benefit from the very rich curriculum materials from the DepEd 2000 revised Basic Curriculum and other curriculum materials from developed countries like Singapore and the United States of America.
