Former San Anselmo Mayor Brian Colbert officially joined the Marin County Board of Supervisors on January 14 as the District 2 representative. Colbert’s swearing-in was a celebratory day at the Marin County Civic Center, which also saw District 3 Supervisor Stephanie Moulton-Peters take her oath for a second term and District 1 Supervisor Mary Sackett selected as Board President.

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 as a Countyemployee. Colbert now represents the entire Ross Valley area following seven years on the San Anselmo Town Council.

A 10-year San Anselmo resident, Colbert was raised in Connecticut and has degrees from Oberlin (Ohio) College and the University of Chicago Law School. He worked on Wall Street, with several tech startups, and for a concierge medical practice in San Francisco. He was elected to the San Anselmo Town Council in 2017, was reelected in 2020, and served twice as mayor.

“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. 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, building a brighter future where opportunity and compassion go hand in hand.”

The ceremony featured his public oath of office, administered by his daughter, and included celebratory elements such as a performance by gospel singers from his district. Supervisor Colbert’s swearing-in is a milestone for Marin County, as he is the first African American elected to the Board since its inception in 1852.

Sackett, who begins her third year representing District 1, will serve as Board President for the first time. Sackett accepted the gavel from District 4 Supervisor Dennis Rodoni, who served in the president’s role during 2024 and was recently reelected to a third term. District 5 Supervisor Eric Lucan will serve as Vice President, and Moulton-Peters will serve as Second Vice President. The leadership changes were formalized at the Board’s first meeting of the new calendar year. 

Sackett represents San Rafael, Marin County’s largest city and county seat, along with unincorporated communities such as Santa Venetia and Lucas Valley. First elected in June 2022, Sackett assumed office in December of that year. A native of Iowa and a 23-year resident of Marin, Sackett practiced law in Marin before joining the County government as a board aide to then Supervisor Damon Connolly. Sackett holds a degree in geography from the University of Iowa and a J.D. from West Virginia University College of Law.

As Board President, Sackett will lead the Supervisors in exercising fiscal responsibility while advancing the County’s top priorities of affordable housing and permanent supportive housing, race equity, climate change and sea level rise, disaster preparedness, County infrastructure, and the recruitment and retention of stellar County employees.

“We have a collaborative Board of Supervisors that is grounded in finding solutions for the good of our constituents, the County overall, and the health of our planet,” Sackett said during her opening remarks Tuesday. “I am focused on the County delivering essential services efficiently and effectively.”

The Board typically meets two or three times a month on Tuesday mornings in the Board chamber of the Marin County Civic Center, Suite 330 in San Rafael. Meetings are conducted both in person at the chamber and also via videoconference to increase public engagement opportunities. Meeting start times are usually 9 AM. All Board meetings are televised live on channel 27 for Marin County subscribers of Comcast/Xfinity and streamed live on MarinCounty.gov. Videos and agendas of the meetings dating to 2005 are archived on the website as well.
