Early Life and Education
Jennifer Lynn Siebel was born on June 19, 1974, in San Francisco, California, and grew up in Ross, Marin County. She is one of five sisters. Her father, Kenneth Siebel, built a successful career in investment management, co-founding Robertson, Colman & Siebel and later running Wood Island Associates, while also developing real estate ventures. Her mother, Judy Siebel, was active in philanthropy and community work.
Jennifer attended Stanford University, where she earned a bachelor’s degree in Latin American studies and participated in athletics. She later pursued graduate business studies at Stanford but eventually turned her focus toward acting and filmmaking.
Acting Career
Jennifer started her career in the early 2000s as an actress, appearing in shows like Mad Men, Life, and Numb3rs, along with independent films. While she gained experience and exposure, she did not achieve major stardom as a performer. Her experiences with the entertainment industry shaped her later work as a filmmaker and advocate, particularly regarding the representation of women in media.
Documentary Filmmaking
In the late 2000s, Siebel Newsom shifted to documentary filmmaking. Her 2011 film Miss Representation explored how mainstream media contributes to the underrepresentation of women in leadership roles. The film premiered at the Sundance Film Festival and sparked national conversations about gender inequality.
Following this, she founded The Representation Project, which promotes media literacy and challenges societal gender norms. Her later documentaries include The Mask You Live In (2015), addressing pressures on boys and men, and Fair Play (2022), which examines workplace inequities and the unequal distribution of unpaid labor.
Role as First Partner of California
Since 2019, Jennifer has served as First Partner of California, after her husband assumed office as Governor. She chose the title to emphasize partnership over tradition. In this role, she has championed gender equity, pay fairness, parental leave, and corporate accountability, blending activism with public service.
Personal Life and Advocacy
Jennifer married Gavin Newsom in 2008. They have four children and reside in California. She balances her public service, filmmaking, and family responsibilities while advocating for policies supporting working families.
She also gained national attention for her testimony during the Harvey Weinstein trial, sharing her personal experience of sexual assault, which reinforced her advocacy for systemic change in entertainment and society.
Real Estate
The Newsoms have owned several notable properties in California. In 2011, they purchased a home in Kentfield for $2.225 million, later selling it in 2021 for $5.895 million. They bought a Fair Oaks home for $3.7 million in 2018, and in November 2024, acquired a Kentfield property for $9.1 million, previously owned by Hyatt Hotels heir Daniel Pritzker.
