The Laguna Academy, considered the largest provincial private secondary institution in Luzon up to the outbreak of the recent war, was established as a solution to one of the pressing educational problems of the times.

Upon the death of the first two presidents of the board of trustees and co-founders of the institution, Don Melecio Fule and Don Zacarias Sahagun (a municipal president of San Pablo who was responsible for the opening of a town government hospital), one of the academy's alumni in the person of Dr. Nicasio B. Sahagun, physician and educator, took the reins of the school administration in 1938.

He and Mr. Alfredo Evangelista, treasurer of the institution, with the moral and material support of the other members of the board exerted much effort in the establishment of a junior normal college.

With the liberation of the city of San Pablo in 1945, the academy resumed its educational mission.

Under its new name, Laguna College, it offers kindergarten, elementary, special science curriculum and RBEC-based high school, college, and graduate school courses which, together, make up a student population of several thousands.
