The institution traces its roots from Engr. Romeo Sustiguer who was managing an agro-industrial machinery company, Green Valley Machinery, during the 1990s. When the demand for industrial machines significantly increased, he faced a situation wherein there were no available skilled manpower that he can immediately tapped for production. Because of the rarity of the skill, Engr. Sustiguer had to acquire expensive labor — workers based in relatively far locations — in order to meet his schedules in the plant facility.

Opportunity presented itself when Mr. Ruden Jose and Mr. Evaristo Abu approached Engr. Sustiguer to start a new school — a training center — at a minimal investment. Seeing training as a strategic solution to his manpower predicament, Engr. Sustiguer proceeded with the  foundation of the school in October 1995. It was then named the Green Valley School of Arts and Technology.

At its initial phase, expenses for the school’s operations was solely financed by the machinery company. But this did hamper the growth of the organization under the leadership of Engr. Sustiguer’s wife, Luz. Mrs. Luz’s enthusiasm and knack for people has helped the organization explore and take advantage of opportunities for growth. The general theme for the courses then covered industry-based technology courses such as mechanical, automotive, electrical and electronics technology

The GVSAT grew in terms of student population and its program portfolio also expanded. The founders then decided to further invest in the laboratory facilities through the additional computers, set-up improvements and the library.

The positive responses to all of these developments were overwhelming prompting the management to look for an annex site for expansion in 1998. From the 4th floor of the Green Valley Building located in the downtown area of Koronadal, an annex center was built in the Lower Aurora street in Koronadal. This paved way for the influx of more students.

Consciousness among the residents of South Cotabato grew further as a result of all of the institution’s efforts. The management responded by developing its existing pool of trainers and faculty. At the same time, the school also ventured into other fields of study such as hotel and restaurant management, computer secretarial and nursing aide.

The success was met with welcome challenges. These include having to cope with the significant increase in enrollment and complying with the many requisites for higher education programs. As a response to the growing population, the management decided to consider transferring to a bigger location in Kilometer 2 of the city.

The first building was able to house hundreds of students. But with the growing population, the need for additional classrooms became a concern. For this reason, expansion became possible with the two major construction projects which  housed classrooms and laboratory facilities.

In 2007, Green Valley underwent major management reorganization. Engr. Romeo Sustiguer, Sr. took a more active leadership position. New policies and systems have been put in place to ensure sustained growth.

During this time, Engr. Sustiguer focused on applying for new courses for TESDA. The end result is that the institution became the no.1 training center in terms of the number of the TESDA recognized course offering. These efforts were complemented by the expansion of facilities such as the business center and the renovation of the HRM laboratory.

In January 2009, RJ Sustiguer became more active in general management functions. His thrust is to bring Green Valley at the forefront of education in South Cotabato through stronger business and industry linkages, application of best practices in education and value innovation in institutional services.

After 14 years of Green Valley’s phenomenal growth, it has yet again embarked on a major undertaking — that is, the construction of a building which is expected to double existing absorptive capacity. Already, this is considered as one of Green Valley’s major milestone as it fortifies itself to be primal force in the education industry of the region.

The new 4 storey building will house more than 40 rooms — which are both for lecture and laboratory. The first phase of the construction is on schedule with target date of completion by June 2010.

Alongside these developments, the institution has also applied for a number of new programs to meet the emerging demands of the educational market. The expansion in the course portfolio is fundamentally prompted by the absence of right quality but affordable program in fields of engineering and hospitality management in the region.

The institution is now also able to leverage on existing strategic partnerships with IBM, a global leader in IT solutions, the UP IT Training Center, the 1st ISO certified IT training center in the country, the Network for Enterprising Women, the Association of Training Institutions for Foreign Trade in Asia and the Pacific and other academic institutions.

To date, Green Valley strongly positions itself as a key learning organization which commits to continual improvements in its system –  scholastic  pursuits, processes, faculty, student services and leadership. Several developments are already being considered in the pipeline with the entrance of school year 2011.
