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.



Hi! My name is Megan Lee, and it’s my pleasure to welcome you to the Omicron Sigma Chapter of Delta Sigma Pi here at UC San Diego. Coming out to Delta Sigma Pi Fall 2021 Recruitment, I was looking to find my community here at UCSD. From being a new transfer student to having 50+ new friendly faces around campus, Delta Sigma Pi has become my safe space amongst UCSD’s student body. Whether it’s late nights at Geisel studying for classes together, ZOOM calls with alumni asking for career advice, or spike ball at the beach with brothers, the dynamic of our organization fosters a healthy balance of our pillars: brotherhood, professionalism, leadership, and service. Through the expansive network of Omicron Sigma Brothers and Alumni, I have never met a more ambitious, passionate, and genuine group of individuals. I strongly encourage anyone interested in expanding their career opportunities, meeting new friends, and challenging their personal and professional goals to come out to recruitment. I am genuinely so thankful for the brothers in our chapter for pushing me to be my best self. I am excited to serve our chapter and the business community at UCSD as the Delta Sigma Pi President and lead the way for other students to find their fit.


Founded in 1907, Delta Sigma Pi is the nation’s first and largest co-ed professional business fraternity, embodying the four pillars of Professionalism, Brotherhood, Leadership, and Service. With nearly 305 collegiate, 55 alum chapters, and over 300,000 brothers worldwide, the network you gain from joining Delta Sigma Pi is incomparable. Our chapter, Omicron Sigma, was founded in 2004 and continues to be a prominent advocate for the business community here at UC San Diego.
