A number of female United States Senators are members of National Panhellenic Conference (NPC) and National Pan-Hellenic Council (NPHC) women’s fraternities/sororities. I suspect there are a greater number of sorority women who are or have been state senators. This is the list of women who have served in Washington, D.C. and not in the state capitals.
