Who we are

Founded in 1899, Delta Sigma Phi is a fraternity built on the principles of leadership, service, and lifelong brotherhood. Guided by our core values of culture, harmony, and friendship, we strive to create an inclusive environment where members can grow into confident, well-rounded individuals. Our mission is to build better men by fostering academic excellence, personal development, and a commitment to making a positive impact on campus and in our communities. With a rich history and a strong network of alumni, Delta Sigma Phi continues to inspire generations of leaders who carry our values into the world.

At SDSU, Delta Sigma Phi stands out as a vibrant chapter dedicated to upholding this proud legacy. From philanthropy events like Sailors Week, where we’ve raised thousands for meaningful causes, to leadership opportunities and social activities that forge lasting bonds, our chapter offers a well-rounded experience for every member. Together, we celebrate our traditions, give back to our community, and prepare for bright futures—all while building friendships that last a lifetime. Delta Sigma Phi isn’t just a fraternity; it’s a brotherhood that inspires greatness and creates connections that endure far beyond college.
