Sigma Alpha Omega (ΣΑΩ) is a nationally incorporated Christian sorority for women, founded at North Carolina State University on January 5, 1998. However, they can trace their roots back to the once co-educational Chi Alpha Omega fraternity founded at East Carolina University in 1987. The sorority was formed after a vote of active members at the NCSU chapter in 1998, and focuses on setting good moral examples for their peers and their community.
