Members of Delta Sigma Theta Sorority, an international non-profit women’s organization, returned to New Orleans for the third time to celebrate their 50th national convention. The gathering, “A Sisterhood Called to Serve: Transforming Lives and Impacting Communities,” not only allowed up to 16,000 sorority members to reunite in the Crescent City, but provided them an opportunity to aid the surrounding community.

On July 30, the organization hosted IMPACT Day, a series of 22 service projects benefitting local non-profit organizations in New Orleans. According to the group, each service event honored of one of the sorority’s founders.

“Delta Sigma Theta has remained committed to supporting the city of New Orleans in post-Katrina recovery efforts since the very beginning,” said the organization’s national president Cynthia M.A. Butler-McIntyre in a statement. “Through financial contributions, donations, rebuilding houses and opening up our homes to the Delta sisters who lost everything in the storm, Delta Sigma Theta has demonstrated our commitment to rebuilding the great city of New Orleans. IMPACT Day is just one more way that we hope to impact the communities of New Orleans.”

In addition, civil rights activist Dr. Dorothy Height’s final book, Living With Purpose: An Activist’s Guide to Listening, Learning and Leading, was unveiled at the convention. Former U.S. Secretary of Labor Alexis M. Herman, who wrote the introduction, described the book as Height’s “final gift” in a statement and said President Barack Obama received the book’s first printed copy.
