Sigma Sigma Sigma is a National Panhellenic Conference organization that seeks to establish sisterhood, to develop strong womanly character, and to promote high standards of conduct among its members. Tri Sigma believes in outreach within the community, especially prioritizing children's health. Notable partnerships in that area include March of Dimes and Boston's Franciscan Children's Hospital. The sisters of Tri Sigma also take part in valuable leadership and personal development experiences at Northeastern and post-graduation and seek to empower each other and women around the world. Your generous donation to the sorority will help advance all of these ventures.
