Who Was Tessa Newsom?
Tessa Thomas Menzies Newsom, known simply as Tessa Newsom, was born in the United States in the mid-20th century. She became best known as the mother of Gavin Newsom, who would go on to become the 40th governor of California.
She was a woman of humility, compassion, and remarkable endurance. Tessa raised Gavin and his sister Hilary largely on her own after separating from her husband, William Alfred Newsom III, a state appeals court judge and close friend of the Getty family.
Despite the family’s social connections, Tessa’s life was not defined by privilege. Her focus was always on giving her children a sense of responsibility, integrity, and empathy — qualities Gavin often credits her for instilling in him.
Early Life and Family Background
Tessa came from modest beginnings, and her life took a challenging turn after her divorce. She dedicated herself to her children while balancing the demands of work and family. The Newsom family’s ties to San Francisco’s civic and business community gave her children access to opportunity, but it was her personal guidance that shaped Gavin’s worldview.
She emphasized kindness and perseverance over wealth or status. Friends of the family recall her as warm, soft-spoken, and determined — qualities Gavin would later channel in his approach to leadership.
Gavin Newsom’s Childhood with His Mother
When Gavin was a child, Tessa Newsom faced significant financial and personal difficulties. Despite those struggles, she ensured that her children received a strong education and a grounded upbringing.
Gavin has often spoken publicly about how his mother worked tirelessly to provide stability for their small family after the divorce. He credits her with teaching him compassion for working families and respect for single parents — themes that would later appear in his social policies as governor.
In interviews, Newsom has said, “My mom was everything. She was the most selfless, loving person I’ve ever known. She gave up everything for us.”
Tessa’s Health Challenges and Resilience
In the 1990s, Tessa was diagnosed with breast cancer, a battle she faced with courage and grace. Her illness would span several years, during which Gavin remained deeply involved in her care.
Her strength during that time profoundly shaped his views on healthcare access and women’s health advocacy. Those who knew Gavin personally during his early political career say that his mother’s struggle reinforced his empathy for families facing medical crises.
Sadly, Tessa Newsom passed away in 2002, just as Gavin’s political career was gaining national attention as Mayor of San Francisco. Her death left a lasting void in his life but also strengthened his resolve to make an impact through public service.
