How It All Started
A Family Dream Baked Into Every Slice
It all started in a small kitchen in O'Fallon, Illinois, where Dewey — a former line cook with a big dream and an even bigger love for pizza — decided it was time to share his craft with the world. In 2010, with a handful of trusted recipes and a stone-fired oven, Dewey's pizza opened its doors.
What began as a neighborhood pizza joint quickly grew into a community landmark. Word spread fast: this wasn't your average pizza. It was something made with intention — real dough, real sauce from vine-ripened tomatoes, and toppings sourced from local farmers whenever the seasons allowed.
Today, Dewey's pizza continues to grow while staying true to its roots. Every pizza that leaves our kitchen is a reflection of what Dewey believed from day one: that good food brings people together.
- Fresh dough prepared in-house daily
- Locally sourced ingredients where possible
- Family-owned and community-focused
- Stone-fired ovens for the perfect crust
