Marilyn Singleton, MD, JD

Dr. Singleton was a board-certified anesthesiologist and past president of the Association of American Physicians and Surgeons. She had given many presentations on health policy and had published numerous articles. Dr. Singleton ran for Congress in 2012 with a message of personal freedom and limited government.

“I reject the unscientific accusation that people are defined by their race, not by their individual beliefs and choices.”
– Dr. Marilyn Singleton (1947–2024)

Dr. Marilyn Singleton was a trailblazer, inspiring everyone around her with her unwavering pursuit of liberty and opposition to the diversity, equity, and inclusion mandates she felt were insulting to everyone involved in the practice and education of medicine.

Her passion started at an early age. As a teenager, she protested California’s Proposition 14, boycotted Woolworth’s segregated lunch counters, and began a relentless pursuit of knowledge.

In defiance of those who said black people couldn’t attend Stanford University, she broke barriers and graduated from Stanford, then the University of California at San Francisco’s medical school, laying the foundation for a storied career in medicine.

While still practicing medicine, she attended UC Berkeley Law School to gain a greater understanding of the intersection between public policy, law, and healthcare. She interned at the National Health Law Project and eventually practiced insurance and health law while maintaining her medical licenses and practice, all the while advocating tirelessly on behalf of her patients.

And as DEI mandates began to sweep the nation, Dr. Singleton adamantly refuted the false notion of “implicit bias,” calling it insulting and degrading. Never one to shy away from taking a public stand, she penned numerous op-eds, sat down for countless television interviews, hosted her own podcast, co-hosted our podcast, and even sued the state of California late last year for its implicit bias training mandate for licensure.

We are proud to share with you Marilyn’s amazing work with Do No Harm on this page. See our tribute video here.
