With many chapters nationally, a brother is never far. We continually strive to promote a strong bond of fraternal fellowship.


Since 1904, Theta Tau has been a leader in engineering. As our open motto describes, we strive to create with whatever we can, helping others wherever possible with our skills.


We represent a professional career, engineering and more. As our third pillar, we take success seriously. Theta Tau wants to see all of its brothers lead successful professional lives.

About Theta Tau


Theta Tau is the oldest, largest, and foremost Fraternity for Engineers. Since its founding at the University of Minnesota in 1904, over 35,000 have been initiated over the years. With emphasis on quality and a strong fraternal bond, the Fraternity has chapters only at ABET accredited schools and limits the number of student members in any one of its chapters across the nation.


The purpose of Theta Tau is to develop and maintain a high standard of professional interest among its members, and to unite them in a strong bond of fraternal fellowship.
