UNITY Week is a campus-wide effort that affirms the diversity represented within the University community and the value and vitality that pluralism brings to our individual and collective experience.   During the week of Feb. 17-27, 2010, Philadelphia University will sponsor its second Unity Week, a collaborative effort by more than 30 committed students, faculty, and administrators to coordinate a series of performances, speakers, opportunities for dialogues, open classes, food, and music.
