Alpha Tau Omega was founded as the first ever national fraternity. It was created in 1865 at the Virginia Military Institute, with the noble ambition of reuniting the northern and southern states in a principled brotherhood at the conclusion of the Civil War. The founders built ATΩ on the values of scholarship, fellowship, and character. ATΩ has an international, extensive network of alumni; no matter where you go in the country or the world, you'll find ATΩs there. Today, ATΩ is popularly known as America's Leadership Development Fraternity because of its strong efforts to engage its members in positive, leadership-oriented lifestyles.

Our Chapter


Founded in 1904, with our historic Maltese Manor constructed in 1920, the Gamma Omicron chapter at Purdue has always been a proud member of the university Greek Life experience. Through campus involvement and strong leadership, we have been recognized in a variety of ways both on and off campus:


  • Athletic Excellence: our chapter historically scores high in intramural activities. 

  • Academic Excellence: our chapter regularly exceeds the all-men GPA, generally within the top 10 average GPAs of all fraternities on campus.

  • Leadership Excellence: our chapter regularly receives excellence awards from our National Fraternity for recruitment and chapter achievements.

  • Service Excellence: our chapter has been awarded the Greek Cup at Purdue University Dance Marathon (PUDM), which is given to the Greek life organization that raises the most money in the build-up to and during the dance marathon, for the past 4 years.  We also volunteer weekly at Natalie's Second Chance no-kill dog shelter, helping them take care of anything they may need.
