The USC Marshall School of Business is the business school of the University of Southern California. The current Dean is James G. Ellis. In 1997 the school was renamed following a $35 million donation from alumnus Gordon S. Marshall. 
The Marshall School began as the College of Commerce and Business Administration in 1920. The Graduate School of Business Administration was established in 1960.  It is accredited as a business school by the Association to Advance Collegiate Schools of Business.  The Entrepreneurship Program, the first of its kind in the United States,  was established in 1972 and is internationally recognized.  It has now been renamed The Lloyd Greif Center for Entrepreneurial Studies. The Pacific RIM Education (PRIME) program was implemented in 1997 as the first ever MBA course of its kind  to require all first year full-time MBA students to participate in an international experience.
The Leventhal School of Accounting was formed within the school on February 7, 1979. All of its classes are offered at the University Park campus in Los Angeles.
The school occupies five multi-story buildings on campus: Hoffman Hall, Bridge Hall, the Accounting building, Popovich Hall and Jill and Frank Fertitta Hall, which houses the Marshall School's undergraduate programs. 
This is the main building of the Marshall School's MBA programs. The $20 million, 55,000 square feet (5,100 m 2) building opened in 1999 as one of the most technologically advanced business school buildings  in the United States. It was named after alumni J. Kristofer Popovich and Jane Hoffman Popovich for their $5 million gift. The hall provides state-of-the-art technology and eight case-study rooms fully equipped with audio-video teleconferencing devices, 13 Experiential Learning classrooms capable of transmitting lectures and presentations throughout the building, more than 1,100 data connections outlets throughout the building, a courtyard, and more than 15 miles (24 km) of fiber-optic and cable wiring in its Modern Career Resource Center.
Bridge Hall houses all undergraduate offices for the Marshall School of Business, which includes the Office of the Dean, Office of Admissions, and the Department of Finance & Business Economics. It also houses a number of classrooms including the original Experiential Learning classrooms.
The H. Leslie Hoffman Hall of Business Administration, which opened in 1973 and stands eight stories tall, houses the Crocker Business Library and Computer Services. It is named for H. Leslie Hoffman, father of Jane Hoffman Popovich. It was designed by renowned architect I.M. Pei.
The Marshall School offers a Bachelor of Science in Business Administration. There are several joint programs that offer studies with International Relations and Cinematic Arts in combination with Business Administration. New students take a business core and have other time to fulfill the USC Core and take elective classes.
The undergraduate program offers a variety of international opportunities.  The Global Leadership Program (GLP) comprises a two-semester seminar on business leadership in China and a spring break trip to China. 
For individuals, Marshall Executive Education offers innovative open enrollment programming with a wide variety of business certificate programs – online and in-person – geared towards professional and personal development. 
Ranked within the top 15 world business research institutions,  the Marshall School offers a full-time doctoral program within the five academic departments. The program generally lasts 4–5 years with up to two years of dissertation. Along working with notable faculty, doctoral students also receive substantial financial aid, such as graduate assistantship and a living stipend, during their study. 
The Marshall School has more than 82,000 alumni worldwide in 123 countries. Its members consider themselves part of the larger USC Trojan family, itself 345,000-strong. This robust network is often cited by alumni as a factor in their successful job searches.     Events at Marshall often emphasize the importance of networking within the Trojan Family. 
For 2015, national rankings of Marshall's MBA program include No. 38 by Forbes, and No. 21 by Bloomberg BusinessWeek. In 2017, Marshall ranked No. 24 by U.S. News and World Report.  In global rankings, Marshall was ranked No. 65 by The Economist  and No. 48 by Financial Times.
