Rebecca Hermosillo: Sonoma County's 1st District Supervisor

Rebecca Hermosillo began her first term as Sonoma County’s 1st District Supervisor in January 2025, making history as the first Latina elected to the Board of Supervisors. A lifelong Sonoma Valley resident and daughter of Mexican immigrants, her journey to public service is deeply rooted in her community and family’s values of hard work, resilience, and giving back. Her leadership is defined by a strong sense of purpose, an understanding of the region’s diverse needs, and a deep passion for service that has shaped her career.

A Commitment to Public Service Before becoming Supervisor, Hermosillo dedicated nearly 12 years to serving the community in the office of Congressman Mike Thompson, where she helped constituents navigate federal agencies, assisted victims of natural disasters, and worked on a range of policy issues. Her efforts spanned a variety of sectors, including healthcare, education, and disaster relief, reflecting her multifaceted commitment to improving the lives of Sonoma County residents. She worked closely with community leaders and local organizations to implement meaningful programs that directly addressed pressing concerns.

Her passion for service began early, with involvement in nonprofits supporting at-risk youth, including her leadership at the Valley of the Moon Teen Center, where she mentored local teens and developed programs to provide life skills and opportunities. Through this role, she forged deep relationships with the next generation, empowering young people to believe in their potential and equipping them with the tools needed for success. Her work in youth services laid the foundation for a lifetime commitment to advocating for those in need.

A Personal and Community-Driven Journey Hermosillo grew up on the Leveroni Dairy, where her father worked as a milker for decades. Raised in a large family of seven children, she learned the value of hard work and perseverance. The lessons she gained from her upbringing—dedication, humility, and service—continue to inform her approach to governance. As a single mother, she put herself through school, earning a degree in public administration from Park University while working full-time. Balancing these responsibilities instilled in her a sense of discipline and a desire to uplift those facing similar struggles.

Inspired by her parents, who once ran Sonoma County’s first Mexican market and restaurant, she developed a deep appreciation for the struggles and aspirations of working-class families. Her personal journey has allowed her to relate to the daily realities faced by many in the community, strengthening her resolve to advocate for equitable policies and accessible resources. She believes in a government that listens to the people it serves and takes proactive steps to bridge gaps in services and opportunities.

Priorities as Supervisor As Supervisor, Hermosillo is focused on key issues affecting Sonoma County, including housing, homelessness, mental health, climate change, and infrastructure. She is committed to ensuring government is accessible and effective for all residents, particularly the Latino community. Recognizing the challenges many residents face, she is working to implement innovative solutions to address these issues, including expanding affordable housing initiatives, increasing mental health resources, and advocating for sustainable environmental policies.

To strengthen ties between government and the public, she has initiated evening office hours in partnership with representatives from state and federal offices, ensuring constituents can seek assistance without appointments. This initiative reflects her belief that community engagement is essential for responsive and effective governance. She has also prioritized collaboration with local nonprofits and businesses to create more job opportunities and economic growth for residents.

A Vision for the Future Hermosillo believes in fostering collaboration to address community challenges. She has served on multiple boards and advisory councils, including Speedway Children’s Charities, Goodwill Redwood Empire, Pepperwood Preserve’s Youth Advisory Council, and the Sonoma County Sheriff’s Latino Advisory Council. Her leadership is driven by a belief that government should serve and uplift all residents, regardless of background. She seeks to ensure that local policies reflect the needs of all constituents and that marginalized voices are heard and represented in decision-making processes.

Beyond her official duties, she remains dedicated to volunteerism and civic engagement, frequently participating in community events, town halls, and educational initiatives. Her approach to leadership is centered on transparency, inclusivity, and a steadfast dedication to public service. She envisions a Sonoma County that thrives through unity, innovation, and forward-thinking policies.

Living in Sonoma Valley with her mother, Hermosillo remains devoted to her family, including her two sons and grandson, Mateo. As she takes on this new role, she brings with her a deep dedication to public service, a commitment to equity, and a belief in the power of community to create lasting change. She sees her role as not just a political position but as a responsibility to empower, inspire, and advocate for a better future for all residents.
