The Jonsson Comprehensive Cancer Center (JCCC) is a cancer research center at University of California, Los Angeles.
The center was originated by UCLA scientists and volunteers who began working together in the late 1960s. The center was formally established in 1974 and was designated as a comprehensive cancer center by the National Cancer Institute in 1976. The namesake of the center is the Jonsson family; entrepreneur and philanthropist Kenneth Alan Jonsson (the son of Texas Instruments co-founder J. Erik Jonsson), along with his wife Diana Gordon Jonsson, made a $1 million gift for UCLA in 1975 to establish the center, and continued to financially support the center over a period of decades.
Joseph W. Cullen served as a deputy director of the center.
The primary sponsor of the center is the Jonsson Cancer Center Foundation (JCCF), a 501(c)(3) entity (established in 1945).
The center employs around 250 physicians and scientists, who engage in clinical activities (i.e., cancer treatment), education, research (basic and clinical), and cancer prevention.
Although based at UCLA, the Center has clinics elsewhere in California, in Westwood, Santa Monica, Alhambra, Irvine, Pasadena, Porter Ranch, Santa Clarita, and Simi Valley.
