District 4
Supervisor Dennis Rodoni is committed to building a stronger, more resilient Marin County and to advocating for the communities of District 4. As the largest and most geographically diverse district in Marin County, District 4 stretches from the coastal villages of Dillon Beach and Muir Beach to inland areas such as Nicasio, Chileno Valley, and the San Geronimo Valley, as well as portions of western Novato, east San Rafael, Corte Madera, Larkspur, and Mill Valley.
Supervisor Rodoni works to address the challenges our communities face and to create opportunities for residents and local businesses to thrive. In his role on the Board of Supervisors, he works closely to ensure local voices are represented in county decision-making. He also makes appointments of community members to advisory boards and commissions, so that diverse perspectives inform county priorities. He is guided by principles of accessibility, collaboration, and transparency, and strives to strengthen public trust and ensure county government remains responsive to the people it serves.
As a member of the Marin County Board of Supervisors, the five elected members work together to set countywide policies, adopt ordinances, allocate resources through the annual budget, and appoint many department heads. Through public meetings, budget hearings, and oversight processes, the Board ensures that departments, from Health and Human Services to Public Works, operate effectively, manage resources responsibly, and provide high-quality services to residents.
Beyond the work on the Board of Supervisors, Supervisor Rodoni also represents our local community on a range of regional committees and boards. He works to advance Marin’s interests in critical policy areas, including, transportation, housing, environmental protection, public health, disaster preparedness, flood control, sea level rise, broadband, regional governance, and more.
