The company quickly established itself as a supplier of choice for major international automotive companies, particularly Ford Motor Company and GM.

Today, Vinnie serves as the Piston Group’s Chairman and Chief Executive Officer. Under his leadership, the Piston Group has expanded from a single facility in Detroit to multiple locations across the Midwest including Michigan, Ohio, Missouri and Kentucky. Mr. Johnson has led the company through successful joint ventures with industry leading firms such as Lear Corporation, Continental Teves and Sachs Automotive.
