La Union Colleges of Science and Technology, Inc. was founded on September 2002. LUCST is the realization of the dream of the founder, Engr. Arturo C. Quinto to share in nurturing the future leaders.

Since the mother school, Northern Philippines College for Maritime, Science and Technology, Inc. has no more room for expansion, the Founder and Chairman, Engr. Arturo C. Quinto looked for more spacious school site. He was able to negotiate for a piece of land lying just a few meters at the back of Bauang Municipal Hall.
