Welcome to the home page of the San Diego Delta Upsilon Alumni Association. Our fraternity was founded in 1834 at Williams College and was colonized at San Diego State University in 1966. Since then hundreds of men have been initiated. Today, we are the most active fraternal alumni association at SDSU with an undergraduate scholarship foundation and mentorship program, multiple chapter advisors, an eleven member board of directors, active committees and plenty of social events in between. We encourage all alumni brothers of Delta Upsilon to get involved with our award winning organization.
