School History

California Prep International School (California Prep or CA Prep or CPIS) was co-founded by Dr. Phakdee Mangmiwatthana (Ph.D.) and Dr. Adelino Libato (Ph.D.) on November 14, 2010.

California Prep is committed to the harmonious development of the whole person for student excellence in academics, character/personality, useful service, and global citizenship. Moreover, it intends to continue its tradition of being among the first two complete e-learning international schools in Thailand which were pioneered by the California Prep Team. California Prep stresses the Core-subjects (Math, Science & English plus Business) with e-Learning plus Talent Development and Self-discipline/Values. The ultimate target is character development with positive attitude and love to mankind and the Most Powerful Spirit or Creator God.

It would have been impossible for California Prep to survive without God's blessings and unimaginable synergy through the family of the late Mr. Bhai Khan Mariam Pongswang. The unwavering support and generosity of the said family through Khun Malinee (Khun Chit), Dr. Hataishanok (Dr. Nok), and Khun Manuschanok (Khun Nat) made the new strategically located campus at Kaeng Khoi (Saraburi) possible. This 17-rai campus and its renovated buildings just perfectly match the vision and dreams of the founders.

Among the first School Board members were Dr. Hataishanok Pongswang, one of the directors at Mitrapap Memorial Hospital; Khun Pom Polcharoen, shareholder of Thongsomboon Club; and Dr. Gideon Samson, Investor representative from CA, USA. Among the first leading personnel of California Prep were Nuengnalin Tawinno, M.A. ongoing (Deputy Director for Operations & PR); James Barrett, M.A. (Deputy Director for Curriculum); Nuttida Intasong, M.A. (Registrar); Jongrak Phenglia, M.A. (Librarian); Russell Rollan, M.A. ongoing (Middle School/High School Head); Ajarn Jidapha Tawinno (Cafeteria Head); Michael Alcaide (IT Administrator); Alex de Guzman, M.A. (IT/elearning consultant).

Other Pre-Construction Pioneers: Michelle Alcaide; Daniela Assimiti; Charity Libato, M.A.; Mervin Gallo; Wichuda Jongjit; Del Libato; and Janet de Guzman, M.A. (Elementary Level Consultant); Meenawan Kadeerak, Anuwat Kadeerak, Celedonio del Rosario, Charidel Libato, Olga Sorokina del Rosario, & Bhahanan Jongjit.

Post-construction pioneer teachers/staff of California Prep were: Juby Arceo, & Pichit Thanthra. Moreover, some personnel were also granted honorary pioneer status such as: Bernie Bugaay (part-timer), Roland Ladrido, Daniel Ramos, Ganee Escondo, Arlene Gabida, and Aysha Abdur Rahman.

At the pioneering years, Dr. Phakdee Mangmiwatthana served as the School Director and Licensee while Dr. Adelino Libato served as the Board Chair and Vice-Director for Academic Administration.
