Welcome to America's foremost professional fraternity for men and women pursuing careers in business.

Delta Sigma Pi is one of the largest co-ed professional business fraternities in the nation and has over 300 active chapters and over 250,000 initiated members. Our Fraternity provides great opportunities for students looking for a head start in the business world.


The Omicron Sigma Chapter is based in sunny La Jolla, California at the University of California, San Diego. Founded in May of 2004, our chapter has seen brothers thrive and grow in brotherhood, leadership, service, and professionalism. Our Alumni network extends from marketing departments to financial planning, and from Disney Pixar to Deloitte.


Since its founding in 1907, Delta Sigma Pi aims to be America’s preeminent professional business fraternity. Part of that founding was to form a brotherhood of people from diverse walks of life, at a time when other organizations excluded certain groups from membership. A great strength of our Fraternity is a membership as diverse as the business world, for which we are preparing our members. We are a mixture of different voices from different backgrounds that challenge fixed ways of thinking and lead us to excellent ideas at both the chapter level and in the business world.





Hello! My name is Wendy Tam and I am excited to welcome you to the Omicron Sigma chapter of Delta Sigma Pi here at UC San Diego. As the foremost professional co-ed business fraternity in the United States, we embody the four pillars of Professionalism, Brotherhood, Leadership and Service. Since our founding in 1907, we have initiated over 295,000 brothers, as well as, founded 305 chapters and 55 alumni chapters across the world. Our chapter, Omicron Sigma, was founded in 2004 and has continued to be a strong proponent for the business community here at UC San Diego.
Over quarantine, I felt the most lost and confused I’ve ever felt in terms of what I wanted to do as a Business-related major. When I came out to recruitment last Fall, I was instantly drawn to the strong and ambitious community of individuals. Whether it's seeking job/internship opportunities, preparing for interviews, or conquering my fears of speaking in front of large crowds, the vast network of brothers and alumni here has never failed to support me in my professional development. Above all, DSP has provided me with lifelong friends who encourage me to develop as a person every day. I am immensely grateful for all the valuable opportunities DSP has provided for me, and I hope it can also deliver a great experience for you!
