Systems Technology Institute (STI) College is the largest network of for-profit information technology-based colleges in the Philippines. This private college system offers a curriculum including business studies, computer science, education, engineering and health care. STI uses a trimestral calendar as opposed to the typical semestral collegiate education program mostly used by Philippine universities. STI has branches all over the Philippines and claims to be the second largest IT-based educational institution in Asia. In 2002, STI obtained a majority share in De los Santos College to create the DLS-STI College of Health Professions. In 2006, they acquired a stake in the De Los Santos Medical Center, now known as De Los Santos - STI Medical Center. STI was organized in 1983, when entrepreneurs Augusto C. Lagman, Herman T. Gamboa, Benjamin A. Santos and Edgar H. Sarte set up the Systems Technology Institute to train people in programming and IT. At first there were two schools, and now there are more than 100. Programs include: information and communications technology, engineering, health care, business & management, hospitality and tourism management.
