General Tiburcio de Leon National High School, also known as Gen. T. de Leon National High School or GTDNHS is a public national high school in Valenzuela, Philippines. It is under the supervision of the Division and City Schools – Valenzuela. Founded in 1969, the school had first served as an annex to Valenzuela Municipal High School. Since 1997, it had become a fully independent high school in Valenzuela. Its location has been moved several times, from Gen. T. de Leon Elementary School, to Tañada Subdivision to its present location in Mercado St. near T. Bugallion Bridge.
Gen. T. de Leon National High School was founded in 1969 under the school extension name Valenzuela Municipal High School—Gen. T. de Leon Annex. Former Valenzuela municipal mayor Gerardo Angeles initiated the creation of the school, more generally of barrio high schools in Valenzuela. Through his effort, the VMHS-Gen. T. de Leon Annex was put-up at Gen. T. de Leon Elementary School compound under Valenzuela Municipal High School, whose principal then was Josefina Avendaño-Lisazo.
There were three classrooms (Marcos Type Building) given to the high school, two were borrowed from the elementary and the barangay hall inside the elementary compound was used as a classroom. Ana D. Cruz was the first chairperson designated to look over the high school.
From 1976 to 1984, Mrs. Rosario Tolentino – Santos was appointed as Head Teacher.
Transfer of Location
In 1984, during the term of Adalia Villasfer as the head teacher, the annex was transferred to a 1,533 sq. m. lot at Karen St., Tañada Subdivision, donated by the Filipino Chinese Chamber of Commerce. Seven classrooms were built through the cooperation and support of the Parents-Teachers Association headed by its president Rodrigo Dimagiba
When Villasfer resigned, Bernardina Echaluce assumed office as officer-in-charge of the school. Julita Cayanan took over in 1991 and the student population started to increase. Efren H. Tanfelix became the Secondary School Head of GTDLNHS in 1992. Under his administration, a three storey-building with 12 classrooms was donated by the national government through the effort of former second district representative Antonio M. Serapio.
In 2005, there had been a major reshuffling of principals in Valenzuela high schools, which appointed Salvacion V. David to be the new principal of the school. The present administration of David initiated significant changes in physical development, staff improvement, and pursuit of quality education. During her term, the school re-transferred to its newer and larger location in Mercado St. near T. Bugallon Bridge. The school building, which was constructed early 2006, was first used in 2007-2008 school year and was inaugurated on December 11, 2007. The acquisition of the new site is a joint effort of David, former barangay captain Alfredo Caiña, and the members of the Local School Board, which includes mayor Sherwin T. Gatchalian, former schools division superintendent Dr. Alma Bella O. Bautista, and second district councilors Lorena Natividad-Borja and Kate Galang.
