The University of San Francisco(USF) is a Jesuit Catholic university located in San Francisco, California, United States. The school's main campus is located on a 55-acre (22 ha) setting between the Golden Gate Bridge and Golden Gate Park. The main campus is nicknamed "The Hilltop", and part of the main campus is located on Lone Mountain, one of San Francisco's major hills. In addition, the university offers classes at four northern California branch campuses (Sacramento, San Jose, Santa Rosa, and Pleasanton), at a southern California branch campus, and at locations in downtown San Francisco, including the Folger Building at 101 Howard Street, and at the Presidio of San Francisco. Its close historical ties with the City and County of San Francisco are reflected in the University's traditional motto, Pro Urbe et Universitate (For the City and University). USF's Jesuit Catholic identity is rooted in the vision and work of St. Ignatius of Loyola, the founder of the Jesuit order.
