About Tri Delta
Tri Delta was founded by women, for women, in 1888 at Boston University when our Founders bravely created a new organization that would “think more of a woman’s inner character than her outward appearance.” Their vision has grown into the dynamic women’s organization we know today.
Today, Tri Delta is a network of nearly 250,000 women, and we are committed to lifelong learning through educational initiatives, transformational programming and relevant personal and professional development.
From supporting Tri Delta’s Foundation—which empowers collegiate and alumnae members through transformational programs, scholarships and emergency financial support—to supporting the life-saving mission of St. Jude Children’s Research Hospital and local children’s cancer charities, Tri Deltas are passionate about serving others.

Get to know Gamma Lambda
The Gamma Lamda chapter of Tri Delta was founded in 1989 at the University of California, San Diego. Our history is marked by flourishing friendships, dedication to our sisterhood, and commitment to philanthropy. In the 2025 Sorority and Fraternity Life awards, our chapter was honored to receive the Panhellenic “Commitment to Philanthropy” award for our work supporting St. Jude’s Children’s Research Hospital. The Gamma Lambda chapter continues to embody our core values of truth, self-sacrifice, and friendship on and around the UC San Diego campus, and extend a home away from home to all of her members.
