Established in 2006, the Graduate Nursing Student Organization and its members seek to support the development of graduate nursing students at St. Joseph's University. The GNSO stands as a link to establish methods of communication between the Brooklyn and Long Island campuses, promote scholarly dialogue and engage in community outreach and education programs.

The organization looks to foster communication and collaboration between its nursing students, faculty members, the University community and other graduate nursing programs. It also looks to provide guidance and mentorship to undergraduate nurses, support educational and professional networking, and promote and encourage participation in the University's activities.
