Meet the Grand Slam Ideas Team
We're Chad and Creighton — two best friends from high school who turned big ideas and backyard games into a business.
Chad is the creative brain behind the madness — a science teacher by day, inventor by night, and the proud mind behind Grand Slam Washers, our patented tailgating game. He was named Chad before it was a meme, and he’s been defying stereotypes (and winning washers) ever since.Creighton brings the heat and the hustle. A former professional baseball player — and fun fact: the fourth player in mlb history to hit a grand slam as their first major league hit — he’s now the guy who keeps our ideas moving. From operations to logistics, he’s the clutch hitter behind the scenes.Together, we’re all about turning wild ideas into real things people love — and having a blast doing it.
