Delta Sigma Pi is a professional fraternity organized to foster the study of business in universities; to encourage scholarship, social activity and the association of students for their mutual advancement by research and practice; to promote closer affiliation between the commercial world and students of commerce, and to further a higher standard of commercial ethics and culture and the civic and commercial welfare of the community. Lambda Sigma was initially founded at Cal State Fullerton in 1986. Our chapter of Delta Sigma Pi guides and shapes students to be strong business leaders of the future. Lambda Sigma's three pillars are professionalism, community service, and brotherhood.
