San Patricio began enrolling its first students in 1958. Located on 200 Serrano Street in Madrid, San Patricio was officially recognised as a Teaching Centre under the Education Act of 1953 (amended in 1957). Its founders were four dynamic entrepreneurs, Ms Luisa Murias, Ms Luz Murias, Mr Jaime Marugán and Mr Gabriel Castellano. Each held passionate views on education. However, they were united in their vision to build a progressive learning environment, which had a clear impact on the school from the beginning. As the first Governing Board of San Patricio, they set a lasting example of outstanding school leadership and a legacy of enduring spirit for all who followed.
