As co-chair of the Gill Foundation’s board of directors, Scott Miller helps guide the giving strategies of one of the nation’s largest private philanthropic commitments to equality and equal opportunity. Together with his husband, Tim Gill, he has helped advance the foundation’s work through long-term investments that expand opportunity, strengthen civic life, and improve quality of life for communities nationwide.

Miller’s leadership is rooted in Colorado. A Colorado native and longtime Denver resident, he has championed sustained, place-based philanthropy that builds common ground across sectors and supports programs and services oriented toward the common good. He helped launch the One Colorado Education Fund, which has supported efforts to preserve and share Colorado’s LGBTQ history through partnerships with History Colorado. That same statewide, cross-community approach has informed Miller’s work guiding the Gay & Lesbian Fund for Colorado, a philanthropic model created by Tim Gill to strengthen Colorado communities through visible, high-impact civic investment.

Under Miller’s strategic direction, the fund has supported work across STEM education, consumer financial protection and efforts to combat predatory lending, public broadcasting and community radio, and other initiatives that serve families and communities across rural, mountain, and urban Colorado. During the COVID-19 pandemic, he led hunger-relief efforts that helped deliver more than 5.6 million meals to Coloradans facing food insecurity.

In 2021, Miller was appointed U.S. Ambassador to Switzerland and Liechtenstein by President Joe Biden and was unanimously confirmed by the U.S. Senate. During his tenure, he strengthened strategic and economic ties with both countries, helped establish the Afghan Trust Fund in Switzerland to distribute Afghan central bank assets for the benefit of the Afghan people, and supported U.S. crisis-response efforts, including Operation Fly Formula to address the baby formula shortage. He finalized the sale of $9 billion in military equipment to Switzerland, some of it manufactured in Colorado, and advanced Colorado’s international engagement, including helping bring Switzerland into the National Guard State Partnership Program with Colorado as its partner.

Miller holds a Bachelor of Science with honors in business administration from the University of Colorado Boulder. He lives in Denver, Colorado, with his husband Tim.
