Through her leadership with the Women's Action Network and her work to establish the Solano Commission for Women and Girls, she has fought to make our community more just and more equal. Margi's life of service is an inspiration to us all.
She created the Vacaville High School Special Education Scholarship to open doors for students with disabilities, and co-created Play 4 All Park to ensure every child in Vacaville has a place to belong.
Proud to announce Margi Stern as the 2026 Solano County Woman of the Year. For 37 years as a speech pathologist, Margi has championed those who often go unheard, and her impact extends far beyond the clinic.
Through her leadership with the Sonoma County Suicide Prevention Coalition and her work at the Sonoma Valley Community Health Center, she shows up every single day for people in their most vulnerable moments.
Proud to announce Maricarmen Reyes Larios as the 2026 Sonoma County Woman of the Year. Maricarmen has dedicated her life to one of the most important and often overlooked causes in our community: suicide prevention.
As Lake County's Geothermal Coordinator and a former member of the Board of Supervisors, she transformed underground water utility systems across Middletown, Lower Lake, and Anderson Springs — a lasting infrastructure legacy that will benefit generations to come.
Her design of the AgHiRE workforce development program is just one example of her hands-on commitment to growing opportunity in Yolo County. It is my honor to recognize her extraordinary service.
As a director at the Center for Land-Based Learning, a member of the Farm Advisory Council for the California Climate and Agriculture Network, and a board member of California FarmLink, she has connected countless people to the land and the resources they need to thrive.
Proud to announce Marisa Alcorta as the 2026 Yolo County Woman of the Year. Marisa has spent her career building the foundation for California's next generation of farmers and agricultural workers.
Every year, I have the privilege of honoring one extraordinary woman from each county in our district with my Woman of the Year award. This year's honorees represent the very best of who we are — leaders, caretakers, and changemakers who give so much of themselves to the communities we call home.
Honored to receive the Grand Award at the 4th annual Stars of Food and Wine. From founding the Congressional Wine Caucus to helping pass the Federal Disaster Tax Relief Act, I'm proud to fight for our farmers, growers, and producers every day in Congress.
16 years ago, we passed the ACA. Since then, I've heard from countless members of our community whose lives changed because of it. People could finally see a doctor, afford their prescriptions, and stop worrying about losing coverage.
