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 Natasha Shetty 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 271,000 brothers, as well as, founded 300 chapters and 52 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.


Entering this university as a transfer student, I had two goals: 1) I wanted to land a career in marketing, and 2) I wanted to increase my friend count from 1 (my roommate). I came out to recruitment seeking a way to help with my first goal, and soon after, achieved my second. Since joining UC San Diego a year and a half ago, I’ve found a family in Omicron Sigma that has unconditionally supported me and always pushed me past my limits.  The vast network of our brothers and alumni have served as mentors that helped me shape both my personal and professional lives. Our brothers continually strive to have a positive impact on the people and communities around them, and it’s incredibly humbling to be surrounded by people that aspire for greatness. Joining Delta Sigma Pi has undoubtedly been the highlight of my college career, and I look forward to seeing it become the highlight of yours!
