Delta Sigma Pi is a co-ed business fraternity founded on November 7, 1907 to foster the study of business in universities, encourage scholarship, social activity and the association of students for their mutual advancement by research and practice.

​

The Orange County Alumni Chapter of Delta Sigma Pi was founded in the summer of 1978 and has been progressing for more than 40 years. Our members are composed of graduates from both local collegiate chapters and brothers that have relocated to Southern California from all over the nation. We pride ourselves on our four main chapter values of Professionalism, Service, Brotherhood and Excellence.

​

As one of the foremost Alumni Chapters of the premier business fraternity in the nation, OCAC prides ourselves on continuously  being a nationally award winning chapter.

​

Surrounded by great collegiate chapters in Orange County, OCAC is an invested part of the histories and futures of collegiate chapters throughout Southern California, including UC Irvine, Chapman University, CSU Fullerton, and Concordia University, Irvine.

​

In OCAC, we know that Delta Sigma Pi isn't just for four years, it's for life. We're always looking to connect with wayward brothers, collegiate and alumni.
