Facebook fan Wendy let us know that Pieology is a great option for dairy-free pizza. They offer Daiya dairy-free cheese alternative and according to their nutrition chart, the whole wheat and gluten-free crusts are made without dairy. In fact, if you are building your own, most of the toppings appear to be milk-free. Keep in mind that the typically dairy-containing sauces like alfredo and pesto are made with milk, but they have options like the red sauce, BBQ sauce, olive oil and more.
Pieology has quite a few locations in California, with a small smattering of restaurants throughout the U.S. See their website or locations, phone numbers and menus.
