The College of Business (COB), also known as Ramon V. del Rosario College of Business and formerly De La Salle-Professional Schools, Inc. (DLS-PSI), is one of the eight undergraduate and graduate schools of De La Salle University (DLSU).
It was established in 1920 as the College of Commerce when the University began offering a two-year commercial course.
In 1931, the Bachelor of Science in Commerce degree was first conferred after a third year was added to the initial two-year program.
Many of its alumni have distinguished themselves, assuming top-level positions in the academe, business and industry, and government, such as José W. Diokno, Alberto Romulo, and Enrique Zobel.
During this time, he brought professors from the Harvard Business School into the country to teach management courses.
