Her work is far from a celebrity side-project; it is a full-time, lifelong commitment that has directly impacted global policy and the lives of countless women.

This campaign is considered groundbreaking, as it was one of the first successful attempts to build a U.S. grassroots constituency around a foreign policy issue specifically focused on women's rights. Her advocacy has involved tireless fundraising, public speaking, and lobbying efforts to keep the issue of Afghan women's freedom at the forefront of international discourse.

A significant early contribution came when Mavis and Jay Leno personally donated $100,000 to help jump-start the foundation's global women's rights program shortly after the Taliban takeover. Her dedication to these causes has earned her numerous accolades, including being honored at events like the 26th Annual Dallas Women's Foundation Luncheon and the Feminist Majority Foundation's events.

The Enduring Power of a Private Marriage

Mavis and Jay Leno’s marriage, which began in 1980, is notable not only for its longevity in the often-turbulent world of celebrity but also for their mutual respect for each other's distinct careers and values.

Mavis famously had a strong aversion to the idea of marriage, stating that she never wanted to be a traditional wife or mother. When Jay proposed, she initially declined, only agreeing after he made a solemn promise that they would never have children.

Their partnership was recently highlighted by their joint public appearances in 2024, including the premiere of the Netflix film "Unfrosted" in April, and an event in May 2024 where Mavis was honored for her advocacy work. These moments underscore the strength of their bond, even as they navigate her advanced health challenges together.
