Family Owned. Customer Focused.

In 1974, Rex Crumpton started an auto parts store and small machine shop on Memorial Drive in Tulsa, Oklahoma. Today, sons Rex and Charlie Crumpton run the place, practicing the same customer-first work ethic their dad taught them years ago. The location may be different. The services may have changed. But customers still call Memorial Machine the best in the business.
