(Martinez, CA) – On Tuesday, March 11, 2025, the Contra Costa County Board of Supervisors appointed Dr. Ori Tzvieli as interim director of health services while the County launches a search for a permanent Chief Executive Officer and Health Director for Contra Costa Health (CCH).

The appointment ensures continuity in the County’s health services and continued progress on key health initiatives.

Tzvieli joined CCH as a family medicine resident at Contra Costa Regional Medical Center in 2000, launching a career in the county’s healthcare delivery system that has led to several leadership roles, including Medical Staff President, Ambulatory Care Medical Director and, most recently, Public Health Director and Health Officer for the county. Tzvieli received his medical degree from the University of California, San Francisco, and a Master of Health Science from the University of California at Berkeley School of Public Health. Dr. Tzvieli will remain the county’s Health Officer while serving as interim CEO and Health Director for Contra Costa Health.

During his time with CCH, Tzvieli has championed collaborative efforts to address opioid addiction, has helped to lead the county’s emergency response to the COVID-19 pandemic, oversaw testing, vaccination, case investigation and contact tracing, laboratory functions, nursing and clinical services, communicable disease surveillance and prevention programs, and an array of work to improve community wellness, from senior nutrition programs to services supporting family, maternal and child health.

He replaces longtime CCH CEO and Health Director Anna M. Roth, who retired in February.

“Anna has been a transformative leader for Contra Costa Health, and while we will deeply miss her visionary leadership, we are confident in and excited about Ori’s expertise and dedication to continue the County’s mission,” said Board Chair and District 2 Supervisor Candace Andersen. “This transition marks an important moment for the County, and we are committed to supporting a seamless leadership change while continuing to prioritize the well-being of our residents.”

During her tenure, Roth oversaw the growth of a $3 billion integrated health system serving more than one million residents. Under her guidance, the County expanded its safety-net services, strengthened behavioral and physical health integration, and launched innovative programs to address homelessness, environmental health, and emergency medical services.

The Board of Supervisors plans to conduct an open recruitment process soon to fill the position permanently.
