We are deeply saddened by the passing of former San Leandro Mayor Stephen Cassidy, a devoted public servant and community advocate whose life’s work centered on strengthening communities and putting people first. He passed away on December 5, 2025, having led with compassion, integrity and a firm belief that government should serve the needs of all.
His leadership was key in the acquisition of San Leandro Hospital. When San Leandro’s only acute-care hospital faced closure, Cassidy partnered with the late Supervisor Wilma Chan to shepherd San Leandro Hospital’s transition to public ownership under Alameda Health System (AHS) in 2013, ensuring generations of families could continue to receive care close to home. Mayor Cassidy led the effort to generate a $3 million donation from the City of San Leandro for the hospital. This action triggered the County to also contribute another $3 million.
Elected mayor in 2010, Cassidy served four years and remained deeply engaged in civic life long after his term ended. A lawyer by training, he formed his own law firm and most recently served as president and chief executive officer (CEO) of the Newark Chamber of Commerce.
Prior to becoming mayor, Cassidy served on the San Leandro Unified School District Board of Education (SLUSD), where he helped advance school bond and parcel tax measures to support student programs and classroom improvements.
Cassidy will be remembered for his steadfast commitment to the people of San Leandro and Alameda County. His legacy lives on in the institutions he strengthened, including AHS, and in the community he served.
We join the community in honoring his life, mourning his loss and sending strength to his family and the many people he served.
