Zeta Psi first began as a local sorority, Omega Psi in 1958. The Zeta Psi Chapter of Sigma Sigma Sigma was installed at The College of New Jersey on April 13, 1997. Since then, the Zeta Psi chapter continues to follow some traditions of Omega Psi that have been practiced at TCNJ for over 50 years.
Our chapter is an organization based on leadership, friendship, and sisterhood. We treasure the alumni of Sigma Sigma Sigma and Omega Psi for laying the groundwork for the Tri Sigma we love and cherish today. Through our initiatives, philanthropy events, and the ways in which we empower others, the Zeta Psi chapter of Sigma Sigma Sigma was named TCNJ's Chapter of the Year in 2017. Tri Sigma is additionally the proud winner of TCNJ Greek Week 2019! Lastly, Zeta Psi is recognized for our Character Counts Week, in which we host events around campus to educate and encourage good character.
