Our Mission

Guided by the values and expertise of medicine and public health, Physicians for Social Responsibility (PSR) works to protect human life from the gravest threats to health and survival.

What We Do

PSR mobilizes physicians and health professionals to advocate for climate solutions and a nuclear-weapons-free world. PSR’s health advocates contribute a health voice to energy, environmental health, and nuclear weapons policy at the local, federal and international levels.
