Tri Delta invests in our members, not just for a few years, but for a lifetime. We are bound by sisterhood, inspired by kindness and committed to belonging, empowering women to lead bravely, act boldly and use our voices to change the world for the better. Our members live out our values of truth, self-sacrifice and friendship each day as they share a lifelong journey of service, sisterhood and growth.

Tri Delta is pleased to announce Elizabeth Howard DiMartino, Boston, as the Chief Engagement Officer. Elizabeth is responsible for leading the organization’s Fraternity Team.
