AdZ experienced a “building boom” beginning with the completion of the Jesuit Residence in 1959, Sacred Heart Chapel in 1961, Gonzaga Hall in 1964, and Canisius Hall in 1967. In 1972, the two one-storey grade school buildings, Berchmans and Kostka halls, were built. By the mid-70s, basic education was well established with an enrolment reaching 381 students in the grade school. In 1976, higher education expanded to include the graduate school which opened an MBA course, the first graduate program in business administration in Region IX. Soon after, other master's degrees followed: public administration, nursing, guidance and counselling, and education. These programs were offered under the guidance of Ernesto A. Carretero, the first president elected by the Board of Trustees of AdZ.
