One of life's valuable lessons is to keep asking questions. The Osher Lifelong Learning Institute at UCSF (OLLI) encourages Bay Area adults to pursue lifelong intellectual exploration in health and the health sciences. OLLI offers participants the simple pleasure of learning — no tests or grades. Supported in part by the Bernard Osher Foundation, this UCSF community education program is sponsored by the UCSF Schools of Dentistry, Medicine, Nursing and Pharmacy, the UCSF Medical Center and the UCSF Public Affairs Department.
