The American Gaming Association (AGA) is searching for a new president and chief executive after announcing the planned departure of Geoff Freeman.
Freeman is stepping down from leading the AGA after five years to take on the president and CEO role at the Grocery Manufacturers Association (GMA).
He will step down from the AGA at the end of July after helping to develop a transition plan and launching a recruitment process to hire his replacement.
Freeman has served as AGA president and CEO since July 2013, when he joined from the US Travel Association to replace Frank Fahrenkopf.
During his tenure the US gambling industry has undergone major changes, from the launch of iGaming in New Jersey during his first year in the job, to last month's Supreme Court ruling that has paved the way for legal sports betting in the United States.
The AGA credited Freeman with fighting efforts by the Internal Revenue Service to decrease the slot tax threshold, blocking the federal government from eliminating resort fees and building a strong relationship with the Financial Crimes Enforcement Network.
"It is a testament to our industry, as well as to Geoff himself, that GMA would look to gaming as a model for managing through dynamic change and complexity to achieve success in both policy and perceptions," AGA chairman Tim Wilmott said.
"Geoff is leaving us with a strong board, a talented team and a more inclusive, strategic, financially sound and forward-looking trade association."
