The Story

Family-owned in the heart of St Marys.

We're a family-owned pizzeria on Crana Street in the heart of St Marys, serving locals with dine-in, takeaway, and pizza delivery since day one. Same kitchen, same family, from the beginning.

Most of our pizzas are named after historic streets across the Nepean area, small markers of the neighbourhoods and people we feed. And yes, one of them really does measure 30 inches across.

The famous 30-inch pizza started as a long-running joke between brothers: build a pizza big enough for the whole table. Founder Mark worked with a local metal fabricator to create a custom 30-inch pan with millimetres to spare inside the shop's 32-inch conveyor oven. The week it launched, people started driving to St Marys from all across Sydney just to see it for themselves, and the photos, reviews, and group dinners haven't slowed down since.

Today, Certified Pizza is known for giant pizzas, family feeds, late-night takeaway, and the 30-inch pizza that helped put St Marys on the map. One pizza. One table. Everyone reaching for the same thing. That's the whole idea, and it always has been.

Took the family out dinner and ordered the 30 inch pizza. Wow. It is huge. Kids were so pumped when they realised how big it is. And the best thing is the quality. It is really good base and toppings. Great idea. Relaxed. Glad we came. Great hospitality, just geniune nice people behind the counter. Looks like a family run business.

These guys are by far one of the best pizzas in the St. Marys/ Penrith area. They definitely have the best customer service out of all the pizza joints I've tried & I've tried a few. I'm a pizza slut. I always recommend Certified Pizza to people. Get a 30 inch in ya!

LOVED the 30 inch pizza it was so good with 4 different toppings and 4 of us could barely get through half! But we saved room for dessert omg those Nutella, biscoff & pistachio twists were 🤤 Would definitely get the 30 inch pizza again it’s like $15 each for 6 people and super fun to eat!
