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.
