About Us
Our Mission
Health Care for All – California (HCA) is dedicated to achieving a universal healthcare system through single-payer public financing. Our goal is for all California residents to have guaranteed, high quality, comprehensive health care.
What We Believe
HCA believes that everybody deserves access to timely, appropriate health care without fear of financial hardship.
Everyone in our society needs the same comprehensive services regardless of personal circumstances (job, income, health condition, marriage or immigration status).
Universal health care is essential to the security and well-being of our society. It is the role of government to ensure it in a way that is most cost-effective for taxpayers.
Seeing health care as part of the public commons—along with public schools and libraries, fire and police protection, water and air safety, transportation and transit, parks and recreation, and national defense—is vital to our social cohesion and strength as a country.

Officers
Officers are elected by the board. As of February 2026, the officers serving are:
Devra Dallman – Chair
After retiring from a career in risk management for an international firm, Devra co-founded the HCA–Napa chapter in 2016 to educate local residents about the need for universal healthcare. She is active in the statewide coalition for a California single-payer system.
She advocates at the national level to end privatization of Medicare, including through the ACO-REACH program enabled by the Center for Medicare & Medicaid Innovation and opposed by the California legislature (AJR-4).
Yi Shepard – Vice Chair
Yi has been actively involved with advocacy for universal healthcare since 2016. In addition to believing healthcare should be a human right in this country, Yi also believes a multi-payer for-profit health insurance system is a fundamentally flawed economic system.
Yi recently retired from a career as a CPA with an international tax firm advising multinationals business clients.
Scott Thomason – Treasurer
Scott taught in the Napa public schools after working as an executive search recruiter and directing special events for Pamakid Runners—including the S.F. Marathon.
He has been active with the Sierra Club Redwood chapter, Napa Valley Vine Trail coalition, and American Canyon Community & Parks Foundation board. He has a journalism degree from the University of Tulsa and served two years in the U.S. Army during the Vietnam War before moving to California.
Harry Baker – Recording Secretary
Harry’s labor activism began in Utah, organizing a union local as a university gardener and heading the state’s public employee labor council.
He is on his county’s labor council and works with Lift Up Contra Costa, which trains diverse young people to run for office. As a San Francisco project manager, he served on the SEIU board, earned a law degree, and led the campaign to transition 4,000 workers from temporary to permanent status.
