Panhellenic Council (PHC)
The Panhellenic Council (PHC) is the governing and representative body including six national (NPC) as well as international and two local affiliated sororities. PHC seeks to support, advocate, and enhance the experience of its member organizations and provide a venue for organizations to communicate and collaborate. Through community service and promoting women's wellness, the chapters contribute to the overall well-being of the SSU community. Through these ideals, the women seek to maintain an environment that upholds their values and amplify the true meaning of sorority.
