The Brothers of the Christian Schools arrived in the Philippines in 1911 upon the request of then Manila Archbishop Michael O'Doherty to establish a Catholic school to train young men for leadership. The Brothers built a campus in the heart of Manila, and De La Salle College began to be known as a leading school for boys and young men. 

Initially, the Brothers formulated a policy whereby they would branch out to the provinces rather than expand the Manila campus. However, they found themselves unable to accommodate the growing number of requests for admission in the elementary grades. Thus, they had to reverse their policy. 

Good friends of the school helped them explore possible locations. Siblings Don Rafael and Atty. Francisco Ortigas asked the Brothers to consider the proposal to purchase and build the school on a six-hectare property behind Wack-Wack Golf Course. After careful study, the Brothers agreed to the terms set by the directors of the Mandaluyong Estate and the deed of sale was notarized on August 10,1956. 

Formative Years (1958-1968) 

The formative years were characterized by efforts to build the physical structures and the administrative foundations of La Salle Green Hills. 

The Central House was built. Soon after, in 1959, the National Shrine of the Divine Child in La Salle Green Hills was inaugurated by Most Reverend Rufino Santos, D. D., Archbishop of the Archdiocese of Manila. In June of the same year, the school opened its doors to primary students with Br. Ubaldo Alphonsus FSC as the first director. On August 24,1960, the school was registered with the Securities and Exchange Commission (SEC) as a non stock, non-profit corporation with the official name of La Salle Green Hills, Inc. 

Two years later, on February 1, 1961, the construction of the permanent school building began with the last of the pioneer Brothers who arrived in the Philippines in 1912, Br. Celba John FSC, doing the honors during the groundbreaking ceremony. Br. H. Gabriel Connon FSC, Auxiliary Provincial of the Philippine Province, laid the foundation stone. 

In 1964, five years after its founding, La Salle Green Hills opened its doors to high school students with Br. Dominic Aquinas FSC holding dual position of grade school and high school principal. A rapidly increasing enrollment led the school administration to take in Br. F. Kevin FSC from De La Salle College to assume the high school principalship in 1966. It was Br. Kevin who started the departmentalization of the different disciplines. 

In 1969, the dome-shaped St. Benilde Hall was inaugurated as a fitting memorial to St. Benilde (Peter Romancon), a La Salle Brother who led a life of piety and charity dedicated to the education of the youth. The hall was conceived by Br. Thomas Cannon FSC, and designed by Architect Gines Rivera. 

A Decade of Development (1969-1979) 

This decade was a period of rapid growth. Even while the Philippines was in socio-economic and political turmoil, La Salle Green Hills had become the preferred school for many families. The Brothers focused their energies on improving the school's facilities, setting up organizational systems, promoting academic excellence and developing a holistic student program, and a practical outreach program for the poor and marginalized.

Physical Expansion, Organizational Effectiveness, and Financial Viability 

Inaugurated in 1969, St. Benilde Hall was first used by the graduating class as classrooms. In 1970, it was also the venue for the Superior General Brother Charles Henry's formal constitution of the Brothers as a separate district. Ten years later, a junior Olympic swimming pool was constructed under the leadership of the then Brother President, Br. Rolando R. Dizon FSC. 

The volatile economic situation challenged the administration to devise ways by which it could sustain its expansion of physical facilities while, at the same time, maintaining its economic viability. Br. Rafael S. Donato FSC launched the Mini-Bond Program, which helped the school restructure its loans into long-term obligations while reducing interest rates. The position of Controller and later, Director of Administration and Finance, was created. Through the efforts of Brothers Richard Bonaventure FSC, Robert Gomez FSC, and Stephen La Brie FSC, the school was able to weather its financial crisis. 

Academic Excellence and Holistic Student Development Program 

To meet the challenge of a growing student population, Brothers Rafael S. Donato and Rolando R. Dizon FSC initiated the split schedule in 1971. This system provided the students with more time to utilize off school hours for athletics, co-curricular and extra-curricular activities and to consult with their teachers on academic matters. 

On March 15,1974 the grade school was granted its first formal PAASCU accreditation. The following year, Dr. Estrella S. Castaneda AFSC, the first non-Brother principal, was appointed. Under her leadership, the Individually Guided Education (IGE) was initiated. In 1975, the preparatory class was revived with its name changed to preschool, and then to Kindergarten 2. 

Outreach and Social Development 

St. John Baptist De La Salle had always been committed to bringing educational services to the marginalized. In 1978, the Adult Night High School (ANHS) was opened. It provided evening classes for underprivileged adults, 18 years old and above, who did not have the financial capability to pursue a high school education. Provided at no cost, students of the ANHS undergo a program which provides them with the basic skills for productive and gainful employment anchored on Christian values. It later expanded into two tracks: formal and non-formal education. 

Continuing Growth and Expansion (1980-1990) 

Academic Excellence and Holistic Student Development Program Values Formation Modules on social responsibility were developed from grades one to fourth year high school and integrated with the curricular offerings for the basic subjects like Christian Living, Reading, Filipino, and Araling Panlipunan. 

Grade School Programs 

A Special Pull-Out Program (SPOP) was introduced in 1982 which allowed academically gifted pupils to fully benefit from the school's regular academic program while providing one day a week for special classes. 

In 1983, Kindergarten 1 was introduced to further strengthen the Kindergarten program. By 1984, computer education started as an optional offering. In 1987, Grades 5, 6 and 7 pupils were enrolled in this program. 

New Initiatives for the Sustained Growth and Development of the School's Manpower Resource 

Several initiatives prospered under the leadership of Br. Rolando R. Dizon FSC. The housing project for the employees was formalized in Antipolo, now known as the Town and Country Heights, home to La Salle College-Antipolo, which he founded. This level of empowerment extended to other forms especially in the involvement of the faculty in decision making on matters that directly affect them through the creation of the Salaries and Fringe Benefits and Multi-sectoral Committees. Furthermore, the culture of research was strengthened and social responsibility modules were formulated which brought about the structured values integration across disciplines and levels 

Organizational Effectiveness and Financial Viability 

The continuing quest for an improved and responsive organizational structure led to an institutional reorganization in 1986. Two major units were set up: The Educational Services Unit and the Administrative Services Unit. Br. Victor A. Franco FSC became Superintendent of the Educational Services Unit while Mrs. Delia C. Domingo became Director of the Administrative Services Unit. The following new offices were created: Human Resource Development Services (HRDS), Curriculum, Educational Networking, Training and Research Office (CENTRO) Department, Religion Team Center (RTC) and the Physical Education, Athletics, Recreation and Sports (PEARS) Center, renamed later as Sports, Athletics and Recreation (SPAR). 

Promotion of the Lasallian Spirit 

The growing awareness of the different sectors of the school community regarding the Lasallian Family concept culminated in the organization of the Signum Fidei Association in 1981. Through the joint efforts of Br. Victor A. Franco FSC and Dr. Estrella s. Castaneda AFSC, its initial membership of 18 expanded to 40 by the end of the decade. One of its noteworthy projects was the establishment of the Signum Fidei Learning Center (SFLC) in 1982, a charity preschool for indigent children. 

In 1984, the school was the site of the First National Lasallian Spirit in Action (LASSA) convention and of the First Asian Mission Symposium which was chaired by Superior General Brother Pablo Basterrechea FSC. Forty (40) Brothers from Asia, Africa, Australia, Europe and the Americas attended the conference. 

In February of 1989, the First Lasallian Youth Congress for Asia and the Pacific Region was held on campus with one hundred twenty-nine (129) foreign participants and sixty-one (61) delegates from various parts of the Philippines participated. 

Living Out the Lasallian Story (2000-2019) 

Throughout the years, LSGH continues the tradition inspired by the vision that propelled the De La Salle Brothers to establish the school for the formation of Christian gentlemen. Following the directions of the 42nd General Chapter of the Brothers of the Christian Schools which was “to give a human and Christian education to the young, especially in schools, with the service of the poor as a priority, in order to evangelize and catechize, to promote peace and justice, accomplished together as a shared mission”, VISION 2011 was conceptualized by both the District and Lay Partners Councils. The Vision states, 

“In relation to our present educational apostolates, we commit ourselves to establish 

a unified District Educational System led by committed, competent and creative individuals 

and characterized by synergy, interdependence and unity of vision”. 

In May 2003, the first Lasallian Family Convocation was convened to create measures to strengthen the sense of Lasallian identity and the deepening of the Lasallian charism among individuals and institutions in the Philippine District. As a result of this Convocation, four documents: The Foundational Principles of Lasallian Formation, the Principles of Lasallian Education in the Philippines, the Principles of Lasallian Social Development, and the Principles of Lasallian Association were formulated to define and clarify the nature of the Lasallian presence and mission in the country today. These four documents are embodied in the Guiding Principles of the Philippine Lasallian Family. The intention of each of the four documents is to articulate the commitments that flow from the three values; spirit of faith, zeal for service and communion in mission which are fundamental to Lasallian identity. Thus, the training and formation of Lasallian associates and partners, the conduct of the Lasallian educational mission in schools, and the socio-political involvement of the Lasallian Family were all anchored on the Guiding Principles. Initially the body that coordinated all activities was the Federation of Lasallian Institution (FLI) headed by the Brother Visitor with representatives from the different sectors as members. 

To further strengthen synergy and national networking among the Lasallian institutions, De La Salle Philippines (DLSP) was established on November 29, 2005. A month later, on December 6, 2005, DSLP was incorporated and recognized by the Securities and Exchange Commission. By May 2006, the different offices of DSLP were in the process of being set up. Issues related to the transition from the DLSU System and the Federation of Lasallian Institutions (FLI) to DSLP were resolved during this period. 

Beginning June 2006, DSLP laid the groundwork for the foundation for long-term programs for all the 18 district schools. The Lasallian Mission Services took over the functions of the former FLI commissions with the special focus on training and formation programs. It now coordinates with the following offices: Vocation Ministry Office, Lasallian Animation and Formation Office, Lasallian Education Commission, Lasallian Youth Office, Lasallian Volunteers Office and Lasallian Justice and Peace Commission. 

Looking forward to 2011, La Salle Green Hills continues to lay down the foundations to answer the call to respond to the challenges of One La Salle. Through these efforts it shall strengthen its commitment to share and work together as one Lasallian Family. 

In 2011, as one of the Eight-Point Agenda of then La Salle Green Hills President, Br. Felipe C. Belleza, Jr. FSC, the school has embarked on a challenging and monumental task of revisiting the school’s philosophy, vision-mission. The agendum as stated reads,

“A realignment of the school’s philosophy, vision and mission with the directions 

of the De La Salle Philippines (DLSP), in light of the celebration of the centenary 

presence in the Philippines is crucial. With the Lasallian Mission Office (LMO) as 

the lead, consultations and meetings will be done to realign our fundamental 

structures with current documents and directions”. (Br. Felipe C. Belleza Jr. FSC) 

In realizing the agendum, the following objectives were identified: 

1. To support the renewal of the LSGH community through the formulation 

2. and dissemination of the revised philosophy, vision-mission of the school; 

3. To ensure alignment of this effort with the DLSP directions; 

4. To promote communion in mission through an inclusive, participative and consultative 

5. process of revising the school philosophy, vision-mission. 

The revision was a painstaking, challenging, and meaningful process that involved three phases: preparatory, implementation, and dissemination. Each phase ensured that consultation with and collaboration of the different stakeholders were accomplished. 

After the revised Vision - Mission was approved by the Board of Trustees on February 13, 2012, the newly revised Vision - Mission of La Salle Green Hills was presented, blessed, and officially read before the highly expectant Lasallian community on the occasion of the solemn visit of the Relic of the Founder, St. John Baptist de la Salle. 

On August 15, 2012, on the occasion of the celebration of the Buwan ng Wika, a Filipino version of the newly revised LSGH Vision-Mission was given to the Head Administrators and Immediate Supervisors for dissemination and implementation. 

The newly revised Vision - Mission Statement has given La Salle Green Hills a much-needed impetus to be more responsive and relevant to the dynamic challenges of the “signs of the times”. 

The Return of a Visionary Brother 

In the year 2013, Br. Victor A. Franco FSC was appointed President of La Salle Green Hills. His appointment was gladly welcomed by every member of the Lasallian community. Br. Vic who became the school’s President during the early 90s was considered visionary and his innovative and collaborative administrative style endeared him to both students and employees of La Salle Green Hills. 

In January 2014, Br. Victor A. Franco FSC convened selected delegates of the Lasallian community for a strategic planning workshop. The LSGH Strategic Plan 2014-2019 was crafted. Towards the end of 2014, the second strategic planning was held in PHINMA Training Center, Tagaytay City. This time, the delegates revisited the Strategic Plan 2014 - 2019 and formulated the three LSGH Big Goals with key results areas that will give direction to the school from school year 2015 to 2020. As an offshoot of this grace-filled reflection process, the delegates specified the objectives, milestones, strategies and action plans through which the Three Big Goals could be realized. 

Guided by a visionary Brother and equipped with a long-term vision, La Salle Green Hills has acquired a renewed zeal to be a beacon of hope to the Philippine society. Its provision for holistic formation of 21st century Lasallian leaders whose competent leadership is anchored on the Gospel values and with special attention given to the development of the culture of helping has become its distinct mark as a Lasallian school. 

Exploring Uncharted Paths (2020-present) 

Integrated School (P-Gr. 12 and AltEd) 

Under the leadership of a brave alumnus, Br. Edmundo L. Fernandez FSC, and an equally valiant Principal, Br. Alexander Ervin T. Diaz FSC, LSGH transitioned to an integrated school in the school year 2020-2021 to ensure a more effective and streamlined learning process from Preschool until Grade 12 with programs for Alternative Education - Adult Night School (ANS) and Alternative Learning System (ALS). The school also implemented a trimestral calendar which allowed more flexibility in the delivery of efficient learning experience. 

Co-educational System 

At the turn of the new decade, faced with challenging educational demands and outcomes, LSGH decided to be co-educational following in the footsteps of all other 15 La Salle Schools in the Philippines and keeping true to the charism of the Founder. The school has since moved to be inclusive in accommodating deaf students and even adult learners and students with special needs, the introduction of a coed system in the basic education was a bolder step towards greater relevance, inclusivity and access to quality Lasallian education for any gender. After pursuing the groundwork for buildings and facilities, policies for Safe Spaces, and programs fit for a coed learning environment, the smooth integration of the first batch of Gr. 11 female students took place in SY 2020-2021. 

Flexible Lasallian Education through Technology and Collaboration at Home (FLETCH) 

In the middle of 2020, the COVID-19 pandemic severely affected the school and was forced to find ways to transition from on site to remote delivery of learning in order to survive the crisis. As one community with faith and zeal, the school seized the opportunity to reimagine LSGH education and to renew its educational program with greater creativity and fidelity to the Lasallian mission. LSGH FLETCH: Flexible Lasallian Education through Technology and Collaboration at Home was introduced. Fletches are the vanes used to provide aerodynamic stabilization in arrows, such as feathers. Just like fletches, the LSGH FLETCH provided our learners more than enough stabilization features to set their arrows straight to their targets.
