Nikola has lived in Muir Beach with her husband Joseph Ferraro since 2005. Although born in San Francisco, the family spent most weekends in Bolinas and with her move to Muir Beach, it is fair to say that she is a life-long West Marinite.
She has a challenging and rewarding career as a pediatric cardiologist for Stanford Children’s Health which takes her to clinics in SF, Novato and Santa Rosa. She enjoys gardening, reading and playing the flute and with what free time is left she participates in Muir Beach volunteer groups such as the MBVFA Memorial BBQ baking team, Neighborhood Disaster liaison and Garden Club. Joining the CSD had been on her radar for several years and Paul Jeschke’s departure from our community and the board provided the opportunity to follow through and become more involved in supporting the wonderful people of Muir Beach.
She was last appointed to the CSD Board in 2023. Term expires in 2024.

Muir Beach has been home to Christine’s family since the 1970s. She has a B.A. in Political Science and Legal Studies from the University of California, Santa Cruz. For eight years, she served the Democratic Party as a Delegate and a voting member of the Democratic Central Committee of Marin. From 2013-2021, she was the Vice Chair of Marin County’s Alcohol and Other Drug Advisory Board to the Marin Board of Supervisors where she advocated for better education, treatment, and rehabilitation services for the community. Since 2016, she has been employed at an Internet and cyber-security company based in San Francisco where she is focused on customer growth and retention strategies. Her husband, Sefton Murray, has been a Muir Beach Volunteer Firefighter since 2017. They are excited to be raising two young sons at Muir Beach. Term expires in 2026

Mary Halley first moved to Muir Beach in 2011, after buying a house that needed some work in late 2009.
