"Never had a sorority been founded so completely and with such depth of meaning from the very beginning."

Delta Delta Delta

it began with friendship

Although there were three women's groups represented at Boston University in 1888, seniors Sarah Ida Shaw and Eleanor Dorcas Pond saw a need for a different organization that would "be kind alike to all and think more of the girl's inner self and character than of her personal appearance." Not only did these two young women create the framework of our organization, but they also created its Rituals and symbols, wrote its constitution and designed its emblems. All was finished on Thanksgiving Eve 1888 when the two embraced each other and declared "Tri Delta is founded." Their vision has grown into the dynamic women's organization we know today.
