Founded in Tulsa in 1934. What has allowed Mill Creek to enjoy over 80 years of business and be ready for many, many more? It is the fact that Mill Creek’s focus has always been on its people. Any company can build a building, stock materials, and buy equipment, but it takes the hiring and rewarding of outstanding people to grow and enjoy eighty years of business. The company with the best people almost always wins and Mill Creek has always worked to have the best people.
