Currently a Member of the Governance Committee, Term Length: August 2024 - May 2025

Dr. Fiona Wilson has been with CCSF for over four years as the Chief Physician for City and County of San Francisco employees. Initially, her role primarily focused on COVID-19 and supporting our efforts to keep our employees healthy, from COVID-19 management to policy development and employee education to supporting our CCSF vaccine initiatives. Our efforts to limit COVID-19 in our workforce helped set us up to have the lowest COVID-19 case rates and deaths compared to other cities around California. She considers the overall health, safety, and wellness of our large and diverse CCSF workforce.

Before joining CCSF, Dr. Wilson was involved with the Brown and Toland Physicians for over 20 years in various roles: initially, as a practicing primary care internal medicine physician and board member representing UCSF, to then joining their senior leadership team where I was Chief Quality Officer and later Chief Medical Officer.  Dr. Wilson was deeply aware of the complexity of health care financing and insurance programs from HMO to PPO, from Medicare to Medicare Advantage, and the many evolving quality programs supporting many aspects of acute and chronic care.

As a practicing primary care internist for many years before a career in healthcare administration, Dr. Wilson was acutely aware of the importance of access to excellent, high-value healthcare. She was also familiar with the life issues of a retiree population as she cared for her aging parents into their 90s, fully cognizant of the challenges and vulnerabilities inherent to aging and the importance of trustworthy, affordable healthcare.

Outside of the Brown & Toland Board service, Dr. Wilson was on the San Francisco Friends School Board for the early years of its establishment as an independent K-8 Quaker school in the Mission and was involved with Partners In Health, a Boston-based international public health care organization since early in its founding. Dr. Wilson serves on the Mt. Zion Health Fund board, which does health and community grantmaking.

Dr. Wilson looks forward to supporting our current employees, retirees, and beneficiaries so they may thrive and be supported with excellent healthcare.
