Rhett Wilson is the Founder and President of Teapot Mountain Advisory, a philanthropic consulting firm advising cultural institutions, presidential libraries, universities, and civic organizations on major-gift strategy and capital campaigns. The firm counsels leadership and boards on campaigns representing hundreds of millions of dollars in philanthropic goals, with clients including the John F. Kennedy Library Foundation, the U.S. Capitol Historical Society, the Mississippi State University Foundation, and the U.S.-Ukraine Foundation.

From 2016 to 2025, Wilson served as Senior Vice President and Chief Development Officer of the White House Historical Association, where he built the Association's first professional fundraising division. Under his leadership, the development team grew from two to more than twenty-five professionals, the donor base expanded from 103 to more than 16,000 annual supporters, and the Association completed an 18-month, $85.5 million campaign to open The People's House: A White House Experience, the museum that opened steps from the White House in 2024.

Wilson is the Founder and Chairman of Innovations in Philanthropy, which holds invitation-only summits for dozens of nonprofit chief executives, chief development officers, grantmakers, and philanthropists under Chatham House Rules. He started IIP because, in his experience, the executives who run nonprofits, the officers who raise their money, and the donors and foundations that provide it seldom have the chance to talk candidly in the same room. The summits convene in Charleston, South Carolina, in the fall. The winter convening follows in Palm Springs, California.

Wilson is also Co-Founder of the Caravanserai Project, a Palm Springs nonprofit that began in 2016 over breakfast with two other founders and a few thousand dollars. It has since grown into an organization with a seven-figure budget serving primarily women entrepreneurs and nonprofit executive directors. Caravanserai hosts Caravan SBDC, a center of the Orange County Inland Empire Small Business Development Center Network, which opened in 2024 and provides consulting and training at no cost to small business owners in English and Spanish.

Earlier in his career, Wilson served as chief development officer for business schools in higher education, including the Johns Hopkins Carey Business School from 2013 to 2016, during the public phase of the University's Rising to the Challenge campaign, which closed in 2018 having raised more than $6 billion. He is an Executive Producer of Promise Me, a documentary about Ambassador Nancy G. Brinker and the founding of the modern breast cancer movement. He advises the U.S.-Ukraine Foundation on its philanthropy initiatives and serves on the board of directors of the nonpartisan LGBTQ+ Victory Institute.

A graduate of Mesa Community College and Arizona State University, Wilson previously served as a city councilman in Kearny, Arizona.
