At over 35,000 members, Theta Tau is the oldest, largest, and foremost Fraternity for Engineers.

As a professional engineering fraternity, we combine aspects found in that of social fraternities and technical-oriented societies to create a community where brothers can form life-long bonds, develop themselves professionally, and have meaningful social experiences.

“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”

“Whatsoever thy hand findeth to do, do it with thy might…”

Ecclesiastes 9:10



We forge lifelong bonds of fraternal friendship, a journey that develops and delivers a network of lasting personal and professional relationships. We foster an inviting, safe, and social environment in which our members become lifelong friends.


We develop and nurture engineers with strong communication, problem-solving, collaboration, and leadership skills that we demonstrate in our profession, our community, and in our lives.


We are known for our service to our college, university and the larger community. Our service projects create a unifying environment for learning and personal growth for our members.
