"Very cool spot with excellent sourdough products. You can really taste the quality and craftsmanship in the bread and pastries. I’m a baker myself (@katascakesaz), so I truly appreciate the skill and care behind what they do here. The flavors are spot on, and everything looks and tastes amazing. It would be great if there were a restroom or at least some hand sanitizer available, as it would make it even more comfortable to sit down and fully enjoy the delicious pastries and coffee. Overall, a wonderful place and definitely worth stopping by. 🙂"

"Proof Bread on Mill Avenue: A Welcoming Gem in Tempe: If you’re strolling down Mill Avenue in Tempe, make Proof Bread at 699 S Mill Ave your stop—it’s one of my favorite spots for genuine artisan baking around here. This family-run place brings real sourdough expertise to downtown, and it’s a solid vibe in the neighborhood. The ham and cheese croissant is a real standout: super flaky with that buttery crisp exterior, opening up to a tender, tangy sourdough inside from their slow fermentation process. It’s loaded with savory ham and gooey, quality cheese—perfect balance for breakfast, a snack, or whatever. My visit was made even better by Aiden, who was exceptional at curating and recommending breads to match customers’ tastes. He really listened, suggested options based on what I like, and shared some great insights on the different loaves—made it feel personalized and easy, especially when deciding among all the options. Beyond that, their sourdough loaves are fantastic—crusty and full of flavor—plus other treats like morning buns and pain au chocolat. They do wood-fired pizzas in the afternoons, and the local coffee pours are spot-on. The atmosphere is bright and laid-back, great for quick grabs or chilling. Proof is committed to quality ingredients and sustainable ways, and you can tell. I highly recommend checking it out, especially for the ham and cheese croissant and some guidance from Aiden. Solid experience all around."

"Absolutely love this bakery, I have been buying bread and pastries from them since they used to be at farmer’s market. Their quality is amazing and consistent over years. I love this new location setup and the staff are amazing. This will definitely be my new favorite spot for snacks and lunch at work."

"We went over the weekend and had a pretzel and a seasonal pumpkin danish. Both were wonderful, the new store inviting, and the team was genuinely happy to see all the new customers!"

"I was looking for some healthy bread and came across this place, so I visited yesterday and the sourdough croissant was sooo delicious! The cashier was also incredibly kind and welcoming. I’ll definitely be coming back often. Highly recommend!"
