Meet The Founder

Sienna Wilson

Great Lakes Goo Is Sienna Wilson's Big Idea: Slime That Teaches Kids Real Business.

Great Lakes Goo was founded by Sienna Wilson right here in Michigan. It started with handmade slime and grew into story-packed slime parties, market pop-ups, and a crew of kids learning how a real business runs: selling, accounting, product management, project planning, setup, and investing. Every jar you take home is an investment in young entrepreneurs.
