Our History

The Alpha Gamma Chapter of Delta Sigma Phi was chartered at Georgia Tech in 1920—over a century ago. Since then, our chapter has consistently made a positive impact on campus and in the Atlanta community. Delta Sigs serve in many campus leadership roles, and the Chapter is consistently among the top fraternities for philanthropy, academics, and athletic achievement.


Delta Sigma Phi was the first national fraternity to be founded on the basis of religious and ethnic acceptance. Embodying that spirit, we were the first IFC fraternity on the Georgia Tech campus to integrate racially in the 1970s. Today, we are one of the most geographically and ethnically diverse fraternities on campus. Our culture of inclusiveness is very much aligned with that of the broader Georgia Tech campus.

Our alumni include highly successful entrepreneurs, business executives, architects, lawyers, public servants, clergymen, and, of course, countless helluva engineers. Just a few of our prominent alumni include:

  • David Perdue, U.S. Senator for the State of Georgia1

  • Michael T. Duke, Retired President & CEO of Wal-Mart Stores, Inc.2

  • Bill Moore, founder of Kelly-Moore Paint3

  • Gus Ramirez, Retired Chairman & CEO of HUSCO4
