Having developed Villa Concepcion – a first class subdivision located along the National Highway at the very front of Barangay BagongPook in Pila, Laguna, the Relova clan initiated by Mrs. Concepcion R. Relova with husband Edmundo A. Relova together with daughter Rosario R.Calo, Mrs. Daisy R. Murriel, Leila R. Noceda and Ma.Teresita R. Fajardo had thought of putting up an educational institution that would be offering curricular programs that are geared towards excellence in Science and Business.
Thus, a 4000 square meters lot in front of Villa Concepcion was chosen as the site of the school where the Relova clan decided to build.
At first, financing the construction of the first building was problematic but it was later solved through a bank loan granted to the Relova family.
Thus, South Greenville School was founded on February 14, 2000.
Rev. Msgr. Renato Cosico, the Parish Priest of San Antonio, blessed the cornerstone of the first SGS four-classroom building which now houses the Preschool Department.
In June 2001, SGS opened its doors to its first enrollees, who numbered at 29. In the same school year, it was granted its Government Recognition from Preschool to complete Elementary School levels. Academic policies were handled by hiring Mrs. Sonia Agapay as its first principal together with Mrs. Dorothy V. Bituin, Ms. Evangeline Quintal, Ms. Loida K. De Leon, and Ms. Eloisa Alfonso as its pioneer faculty members.
Having felt the need for more buildings due to its increasing population, SGS management decided to put up a two-storey ten- classroom building in 2003. From 29 pupils in school year 2001-2002, the population grew to 178 in SY 2002-2003.
In the following school year, first and second year high school courses were also offered. SGS curricular programs were then centered on science and business. Facilities were added such as the construction of an administrative building in front of the school and additional classrooms.
In School Year 2004-2005, third and fourth year high school curricular years were added to complete the secondary course. It was in the same year that SGS has its first high school graduates.
Today, SGS runs as a corporation with the following Board of Trustees composed of: Rosario R. Calo, President; Daisy R. Murriel, Vice President/Treasurer; Leila R. Noceda, Corporate Secretary; Ramon E. Relova, Auditor; Regina Pauleen R. Calo, Anna Monica R. Noceda, Maria Antonette M. Cordovilla, Directors. SGS Administration is composed of: Rosario R. Calo, the School Directress and Caxandra V. Buenviaje, the School Principal. There are now 21 faculty members in the high school, elementary school and preschool departments.
