The first group of Brothers, nine in numbers, arrived in Manila in 1911 upon the invitation of the Archbishop of Manila to establish a college of standard. Paco was the original site of the Brothers’ first school, and later, in 1921, a new building was erected on the present site at Taft Avenue. From this modest beginning, the pioneer effort of the first La Salle Brothers developed until present. There are eighteen district schools and a number of La Salle supervised schools throughout the country.
The La Salle Brothers came to Bacolod City in response to the ardent invitation of the Negrense who felt a great need for the type of education the Brothers were offering through a 10 hectare donation of the late Hon. Alfredo Montelibano, Sr., La Salle - Bacolod came into existence.
In July 1952, with 189 graders ranging from Prep to Grade 5 and a teaching force of seven, La Salle College - Bacolod formally opened. Three of the faculty members were Br. Dennis Ruhland FSC, Br. Hugh Wester and Br Felix Masson and the fourth Brother, Br. Gratian Murray, joined in September of same year. The following year, Grade 6 was added.
During the school year 1952 - 1953, the parents requested for the opening of the high school department. On February 9, 1952, cement footings were poured for the first high school wing. Classes opened in 1953 with 24 freshmen, all males. At first, the Brothers accepted student - boarders, there were 56 of them under the supervision of Br. Gratian Murray. The present laboratory and lecture hall served as their sleeping quarters and study hall.
In its second year of operation La Salle had 453 boys in the three fledging departments. School year 1977 -1978 marked the Silver Jubilee of the founding of La Salle - Bacolod. Numerous activities were scheduled to commemorate fittingly to the foundation. In 1978, the Grade School received its PAASCU Accreditation while the High School received its Accreditation in 1980.
At the end of the school year 1984 - 1985, the institution decided to place under one administration the elementary and secondary levels to compose basic education program for La Salle - Bacolod, thus the birth of the La Salle Bacolod - Integrated School.
The effort was a practical move since it was felt that the elementary and secondary levels should progressively and interruptedly form one continuum. Such move would be for the overall betterment of the students’ education.
Since 1986, La Salle has accepted as part of its clientele, Kinder and Prep Girls. It was not until 1987, however, that the Board of Trustees officially handed its decision to turn coed both the grade school and the high school. The inclusion of girls in the once exclusive school for boys has not drastically changed the school’s mission statement. The school’s objectives remain basically the same. However, changes have been made regarding the manner by which these objectives are attained. In a nutshell, the objectives can be summarized into: 1) Wholistic Development, 2) Social Awareness and Involvement, 3) Academic Excellence, 4) Concern for the poor, 5) Love for one’s country and being a Filipino.
July 5, 1988 was another milestone for La Salle as it marked its elevation to university status.
The effort to attain university status was initiated in 1982 by Br. President Rafael Donato, FSC. It was continued by his successor Br. Victor Franco, FSC and was completed by Br. Rolando R. Dizon FSC.
The University of St. La Salle became the first institution to be elevated as a university after the EDSA revolution and also the only one under President Corazon Aquino’s administration.

The school was granted a “clean” re-accredited status for a period of five years. This was an affirmation that the school has successfully accomplished its Vision - Mission for the school.
