Don Gregorio Anonas founded Santa Cruz Academy then, Western Luzon Academy in 1926. In 1933, it was bought by Mr. Arsenio de Perio and operated it under its old name until it was finally changed to Santa Cruz Academy in 1936. The name was again changed to Santa Cruz Junior College in April 1951 when it started to offer a two-year B.S.E.E. – E.T.C. and a complete secondary course. In 1956, the school again used its old name, the Santa Cruz Academy still offering complete Elementary and Secondary courses, two year B.S.E.E. – E.T.C. and Secretarial courses.

In line with the Society of St. Columban’s thrust of strengthening faith through Catholic Education, the Columban Fathers headed by Rev. Fr. Kieran Heneghan then, the parish priest of St. Michael Parish, Sta. Cruz, Zambales offered to buy the rights to operate the school. On July 6, 1965, the right to operate the school was finally sold to the Columban Fathers minus the Elementary and College Courses which were retained by the De Perio family.

The transfer of the school’s management into the hands of the Columban priests was a realization of a dream, of putting up a Catholic School in this part of the province.

Since its incorporation on February 3, 1967, the school has been managed by the Columban Fathers using the same name SANTA CRUZ ACADEMY, INC. and was moved to its new site located in front of the Catholic Church with the following Administrators in succession:

In 1983, there was a Proposed Addition of the building (Building Number 3) of Santa Cruz Academy, Inc. It added six classrooms under the directorship of Rev. Fr. Paul McGee and continued by Rev. Fr. Edward McKenna.

After the three consecutive decades, in April 1997, the Columban Fathers turned over the management of the school to the Diocese which continued its unstinted and loyal service to God and country by blending the wisdom and experience of the times trying to cope with the advances in science and technology without sacrificing the spiritual formation of the students. The Filipino Diocesan priests who became the school directors were Rev. Fr. Ermesto C. Raymundo, Rev. Fr. Renato Roque Villanueva, Rev. Fr. Jaime Escurzon, and Rev. Fr. Emmanuel Jose S. Montes.

In April 1991, there were Structural Repairs of the school building under Rev. Fr. Michael Duffin.

This K to 12 Program, though it covers Kindergarten and 12 years of Basic Education: Six (6) years of elementary education, Four (4) years of Junior High School, and Two (2) years of Senior High School (SHS) for the reasons of giving ample time to the students to have their mastery of concepts and skills, develop a lifelong learning, and prepare them for tertiary education, employment, and entrepreneurship, here at Santa Cruz Academy, Inc., started its Junior High School implementation in the Academic Year of 2012 – 2013.
