Sarah Ranney, Director of the Sierra Club San Francisco Bay Chapter, also chaired the Club’s Climate Literacy Committee and co-founded the California Youth Climate Policy Program. In 2024 she left a 20-year corporate career to devote her time to helping guide the chapter into its second century. A Berkeley resident and mother of two, Ranney champions environmental advocacy, climate justice, and coalition-building to expand the Sierra Club’s local impact during this decisive decade for climate action.
