OLLI-UA is spread over the greater Tucson regions with four centers of activity, which we refer to as "Campuses."  Our Green Valley campus operates to the South; Northwest Tucson covers Marana and Oro Valley to the north; the Central Tucson campus is located at the U of A; and our newest site is Southeast Tucson, near Vail and Rita Ranch. Each campus is distinct in the length of its classes, the fees it charges, and the locations where classes are held. See specific locations of each campus under its informational page.

All campuses share a commitment to providing anyone over age 50 who has a desire to keep their mind active with opportunities to engage challenging subject matter and connect with members, the University of Arizona, and the larger Tucson community. Not only does OLLI-UA offer intellectual stimulation, but each campus hosts several social events each year and participates in community involvement activities.

All OLLI-UA campuses are heavily volunteer driven. Members are strongly encouraged to get involved by helping with curriculum, social activities and a host of projects in which many hands make light work.
