On March 26, 1983, twenty-five members and five honoary members chartered the Zeta Tau Sigma Alumnae Chapter. It was the largest chapter to ever be chartered in the Northeastern Region. In keeping with the sorority's mission statement, the chapter participated in and continues to contribute to various community services throughout Prince George's County, MD. The chapter advises the following undergraduate chapters: Epsilon Lambda Chapter (Bowie State University), Eta Beta Chapter (University of Maryland College Park), Mu Pi Chapter (Capitol College) and Omicron Epsilon Chapter (George Washington University).
