Former San Anselmo Mayor Brian Colbert officially joined the Marin County Board of Supervisors on Jan. 14 as the District 2 representative. Colbert’s swearing-in was a celebratory event at the Marin County Civic Center that coincided with the swearing in of District 3 Supervisor Stephanie Moulton-Peters for a second term. District 1 Supervisor Mary Sackett, who has been selected as Board President, took her oath of office that day.
Colbert was elected in November 2024 to replace retired District 2 Supervisor Katie Rice, who served in that role since 2011 and completed 20 years of service as a county employee.
Colbert now represents the entire Ross Valley area following seven years on the San Anselmo Town Council.

“As your newly elected official, I am committed to working tirelessly for the people of Marin County,” Colbert said. “Our county’s unique and distinct character — its natural beauty, diverse communities, and innovative spirit — makes it a place like no other.”
Colbert continued, “I will approach every challenge through the prism of preserving these values, focusing on solutions that promote economic vitality, environmental stewardship, and resilience. My pledge is to listen to your concerns, act with integrity, and ensure that every voice is heard as we tackle the issues that matter most and building a brighter future where opportunity and compassion go hand in hand.”
