Peterman Lumber, Fontana CA

I do custom woodworking and this is the best spot, they will mill for you, have multiple grades available, and a good selection of sheet goods. Not a big fan of the new way they calculate board feet with the stick, but it's faster and easier on the employees so I get it. Setting up an account with them was a breeze and my sales rep has been incredible thus far. Not sure if they carry much in the way of live edge slabs if that's your thing. They supplied all the walnut for my last project.

Awesome place, you can find almost any kind wood here in very good quality. Customer service is great. This will be my go to place for quality lumber.
