Our Roots

State Supply was founded in St. Paul, Minnesota in 1933 during the depths of the Depression by Italian immigrant Joseph Lombardo. Desperate to feed his family, Joe took the bold step of starting a new company from the trunk of his 1926 Dodge four-door sedan.

In the early days, Joe's method involved taking a customer'sorder down the street to a local supplier, where he bought the needed products. He returned to the customer and presented the order, marking up the products to make a small profit. Today, the world calls this one-sourcing—during the Depression, it was called survival.

State Supply not only survived the Depression, but World War II, along with a devastating fire that destroyed their first building in 1962. Through it all, the folks at State Supply dug their heels in and kept growing

Today, a third generation of Lombardos lead State Supply. While the company remains humble to its St. Paul roots, State Supply now operates on a much larger scale, with more than 50,000 customers and sales measured in the millions.
