Friendship, Sisterhood, Belonging

Tri Delta was founded by women for women, when our Founders bravely created a new organization that would “think more of a woman’s inner character than her outward appearance.” In Tri Delta, you are a unique and valuable part of the whole.

We don’t want you to come here and be like us. We want you to come here and be you.

Membership Information

Our membership drive is under way for the 2025 - 2026 year. By joining and paying dues, you are supporting the programs of both National Tri Delta and our local Philadelphia Main Line chapter.

As of August 1, all alumnae members can now pay national and local dues through My Tri Delta. Alumnae members should visit their My Tri Delta profile and click on the “Alumnae Member Status” tab in the menu across the top of the page. Based on your current alumnae member status, you’ll be asked to pay your dues or level up. Once you click the action button, you’ll be taken to the centralized system to pay your Fraternity and local alumnae chapter member dues. https://mytridelta.tridelta.org

Any member who has resigned from Tri Delta or whose membership has been terminated may make one request for reinstatement. To learn more and to start the reinstatement process, please email membership@trideltaeo.org.
