Pacific States University(PSU) is a private, non-profit, secular, co-educational institution of higher learning. In 1928 William G. Buffinger, a sound engineer, famous for his influence in the movie industry, founded the Radio Institute of California, the forerunner of PSU. In 1939 Dr. Harry W. Evans reorganized the school as Pacific States University with a charter from the State of California authorizing the granting of degrees. For several years the University was under contract to the United States Government for the training of electronic engineers for the armed forces of our country. As many as 400 students per year completed the prescribed courses in this technical area. PSU thereafter continued to specialize in Electronic Engineering, a program phased out in 1997.

A major reorganization of the Board of Trustees in 1964 brought new interest in the expansion of curriculum together with the offer of quality education to students of more diverse backgrounds. The offering of a Bachelor's of Business Administration (B.B.A.) with five concentrations became so popular that the Trustees added a Master's (M.B.A.) with five concentrations and a doctorate (D.B.A.) in International Business. PSU has continued its interest in preparing students in technical fields which is reflected in the degrees in the Bachelor of Science in Computer Information Systems (B.S.C.I.S.), the Master of Science in Information Systems (M.S.I.S.), and the Master of Science in Information Systems (M.S. I.S.)

The University has maintained two successful long-standing non-degree programs: the English as a Second Language Program and the Accounting Certificate Program with a very impressive pass rate for students who sit for the C.P.A. exam

More than 12,000 students have received their degrees from the University and taken their places of leadership in the realms of commerce and technology throughout the world. The student body and excellent faculty are truly international. They have come from more than 100 countries and represent a cross section of the most able minds to be found anywhere. Especially notable is the distinguished faculty who hold degrees from Columbia University, the London School of Economics, McGill University in Canada, Seoul National University in Korea, the University of Southern California, Pepperdine University, Claremont Graduate School, and the University of California, Los Angeles, to mention a few.

In 1996 the Accrediting Council for Independent Colleges and Schools, an agency approved by the U.S. Department of Education in Washington, DC, granted accreditation to PSU which has maintained that status ever since. Successful steps are underway in applying for regional accreditation as well.
