Our Pillars

Professionalism, Service, Brotherhood

Theta Tau’s mission is centered on three pillars; Professionalism, Service, and Brotherhood, each of which plays a distinct and essential role in shaping members into well-rounded engineers and leaders. These pillars are interconnected values that guide how members grow, act, and support one another.

Professionalism

Crafting engineers with integrity.

Professional Development prepares members for success in engineering and beyond. It emphasizes technical competence, ethical responsibility, leadership, and effective communication while reinforcing the expectation that members represent the fraternity and the engineering profession with integrity.

Through hands-on projects, professional workshops, resume and interview preparation, and networking with alumni and industry professionals, members grow in confidence, accountability, and career readiness.

Service

Engineering with heart.

Service reflects Theta Tau’s commitment to using engineering knowledge and teamwork to benefit others. This pillar emphasizes giving back to local communities, supporting philanthropic causes, and applying technical skills to solve real-world problems.

Beyond technical service, it promotes empathy, social responsibility, and the belief that engineers can positively influence the world.

National History

Since 1904

Theta Tau is the oldest and largest co-ed professional engineering fraternity in the United States. Founded at the University of Minnesota in 1904, the organization has shaped engineering students and professionals through brotherhood, professional development, and service.

Our Delta Gamma chapter is part of Theta Tau’s Western Region, a network of chapters and colonies across the Southwest and West Coast that collaborate, share traditions, and support each other.

From its founding by engineering students, Theta Tau has grown into a nationwide network that still centers the same mission: developing leaders for service, profession, and society. That legacy shows up in the way chapters invest in mentorship, ethics, and real-world engineering impact.

Delta Gamma carries that tradition forward by building campus partnerships, creating professional opportunities, and showing up for the communities we serve. The result is a brotherhood rooted in history and driven by what we do today.
