Colegio San Ignacio de Loyola is an all-male, Catholic, Jesuit, college-preparatory school founded by the Society of Jesus in San Juan, Puerto Rico, in 1952. It has educated some of most influential figures of Puerto Rico, such as Ruben Berrios and Raúl Juliá. It is considered a college prep school since all of its graduates go on to colleges, outside Puerto Rico in half the cases, mainly in the continental United States, often at top-ranked colleges and universities such as Boston College, Duke University, Georgia Institute of Technology, Columbia University, Cornell University, Georgetown University, Princeton University, Harvard College, Massachusetts Institute of Technology, University of Pennsylvania, and Yale University.
