Physicians for Social Responsibility — Los Angeles (PSR-LA) advocates for policies and practices that improve public health, eliminate nuclear and environmental threats, and address health disparities. At PSR-LA we recognize that the physical and social environment often determines health status – we are committed to addressing that reality. Our work is grounded in science, and the lived experiences of health professionals and their patients. We are guided by the precautionary ideal to foresee and forestall damage to human health and the environment. Within our work we focus on health, the environment, social justice, and public policy.
