There are nearly 4,000 plus SigEp alumni living in the Washington, DC metropolitan area and a growing number of them call D.C. Delta, American University, their alma mater.

Membership in Sigma Phi Epsilon is a lifetime experience. All SigEp uphold the tradition of "Lifetime Responsibility of Brotherhood." As such, we have come together as alumni to strengthen a bond that was created on the campus of American University. We are men of character and purpose, upholding the principles of Virtue, Diligence, and Brotherly Love.

The alumni network of SigEp is growing larger with each passing day, were brethren are always reaching out a hand to help our undergraduates on their journey throughout life.
