His first racing job was selling tires in South Boston and working for driver Ashton Lewis on his late model team. From these humble beginnings, Barker has become not just a crew chief at NASCAR’s highest level, but a voice for NASCAR, for crew chiefs and for the GEICO entry. Barker has written a variety of magazine columns over the years and has been a regular guest on NASCAR RaceHub on FoxSports 1. He began his motorsports career working in the Late Model Sportsman Series for Ashton Lewis while still in college. Barker has since overcome his injuries to be a respected crew chief and one of NASCAR's most brilliant minds.
