Miller has previously worked as Senior Vice President at the Business Roundtable, where he helped grow the organisation’s brand and advocacy footprint in Washington, leading to the association’s outreach to Capitol Hill. He also has senior level experience at the US Chamber of Commerce.
Tim Wilmott, CEO Penn National Gaming and Chairman of the AGA Board of Directors, said: "Bill’s extensive work with federal policymakers and as a seasoned leader of membership and industry advocacy organisations was critical to our decision.
"He joins a successful organisation at a time when our industry is enjoying great momentum, thanks in part to a major policy achievement – the ending of the federal sports betting prohibition. On behalf of the AGA Board, I am excited to welcome Bill to the team."
Miller replaces Geoff Freeman, who left the organisation in August earlier this year.
Wilmott added: "The Board is extremely thankful for the leadership of Stacy Papadopoulos and Sara Slane, and the commitment of the entire AGA team during this period of transition."
