About Us

The Physicians Committee combines the clout and expertise of more than 17,000 physicians with the dedicated actions of more than 175,000 members across the United States and around the world.

The Physicians Committee is a 501(c)(3) nonprofit organization, headquartered in Washington, DC. Our efforts are dramatically changing the way doctors treat chronic diseases such as diabetes, heart disease, obesity, and cancer. By putting prevention over pills, doctors are empowering their patients to take control of their own health.

And we are also building a new way of viewing research. Since 1985, the Physicians Committee has worked tirelessly for alternatives to the use of animals in medical education and research and for more effective scientific methods.

Our staff of physicians, dietitians, and scientists is working with policymakers, industry, the medical community, the media, and the public to create a better future for people and animals.


The Physicians Committee is dedicated to saving and improving human and animal lives through plant-based diets and ethical and effective scientific research.


Creating a healthier world through a new emphasis on plant-based nutrition and scientific research conducted ethically, without using animals.
