The FSGA was previously known as the Fantasy Sports Trade Association but recently rebranded to encompass gaming and sports wagering.
On the board, Walters teams up with representatives from FanDuel, DraftKings and several other renowned fantasy sports and gaming organisations.
Walters said: "Having operated a fast-growing business in the online gaming and sports betting market in Europe for more than 12 years, Gambling.com Group has accumulated a wealth of experience that can be leveraged in the fast-growing US market.
"One aspect we look forward to working with the FSGA is in helping to educate and inform legislators and policy makers about what good sports gaming policy looks like, much like the association did with fantasy sports."
