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.
