Celine Mactaggart

Celine is a nonprofit founder, data privacy activist, and skin cancer advocate. She is the Co-Founder of Californians for Consumer Privacy, the advocacy organization that created the country's first comprehensive data privacy law, the California Consumer Privacy Act (CCPA), which passed unanimously in the state legislature in 2018. To give Californian consumers even stronger rights, her organization created a statewide ballot initiative in 2020, the California Privacy Rights Act (CPRA)/Proposition 24, and nearly 9.4 million people voted to pass the groundbreaking law, giving Californians the strongest data privacy law ever enacted in the United States. She is also the founder of Shine Safe, an advocacy nonprofit founded to raise awareness for skin cancer prevention.

Celine has over 15 years of nonprofit leadership experience that centers on expanding healthcare access and strengthening education, including being the former Chair of Women in Leadership and Philanthropy at the University of San Francisco, a Trustee at Cal Performances at UC Berkeley, and a Regent of St. Mary's College of California. She received an MS in Nonprofit Leadership from the University of Pennsylvania, where she is a member of the Dean’s Alumni Advisory Board at the School of Social Policy & Practice.

A native of Oakland, Celine lives in the Bay Area with her husband and three children.
