WHo are we?

The Alpha Chi Chapter was originally founded at Washington University in St. Louis in 1928, and has been extremely active in the Olin Business School community since its reinstatement in the 1990s. Boasting one of the largest collegiate memberships among Delta Sigma Pi chapters, the Alpha Chi chapter offers brothers the opportunity to develop professionally, form lifelong relationships, and explore opportunities both on campus and in various professional fields.

Our Chapter prides itself on the involvement of our brothers and their commitment to scholarship, service, and each other. Our brothers are involved heavily in campus life, have held various internships across multiple industries, and remain in touch with our chapter once they graduate and enter the workforce. Our alumni network, consisting of hundreds of brothers, has helped brothers with everything from internship placement to finding housing following graduation.
