Big Grin Fireworks is a family-owned, community-rooted fireworks company operating 13 locations across Metro Atlanta. What sets Big Grin apart is their deep commitment to the communities they serve — 30% of gross stand sales are donated to the local American Legion veterans fund, making every purchase an act of community support. With the Guinness World Record for the largest gender reveal and a growing social media presence, the Semi-Quincentennial represents a once-in-a-generation opportunity to amplify that mission.
