Psi Psi Psi

Tri Psi is the only Greek-letter mothers' sorority and the only international sorority for mothers of fraternity women.


Sarah Ida Shaw, a founder of both Tri Delta and Tri Psi, saw the benefits of a strong mother-daughter relationship.Tri Psi is a great organization that not only helps support our Tri Delta daughters, but helps build special friendships with other Tri Delta mothers. We welcome all mothers, step-mothers, and foster-mothers to become a part of this fantastic organization.

A minimum number of 10 interested mothers are all that is needed to start a new chapter! Please read through the Tri Psi section of the Tri Delta website for more information about this exciting group of women. You can also visit for details.
