Delta Delta Delta (Tri Delta) was created by two women at Boston University who saw a need for a different form of a sorority, even though there were already three women’s groups on campus. They set out to start an organization that was more inclusive of everyone and looks at a person more on what’s inside than their physical appearance.
Their founders are Sarah Ida Shaw, Eleanor Dorcas Pond, Florence Isabelle Stewart, and Isabel Morgan Breed. Photos from tridelta.org

Tri Delta’s purpose is “to promote and develop mutually beneficial relationships between the Fraternity and the colleges and universities where the Fraternity has established chapters, to develop qualities of unselfish leadership among its members, and to encourage them to assume, with integrity and devotion to moral and democratic principles, the highest responsibilities of college women.” (tridelta.org)
Their philanthropy is to treat and defeat childhood cancer. They’ve partnered with St. Jude and over the years have raised more than $75 million in support of them! Tri Delta also has a scholarship program in place for both undergrad and graduate school students.
