The newest member to join the exclusive club is Dublin, Ohio-based auto parts manufacturer Modular Assembly Innovations L.L.C., run by CEO Billy R. Vickers. The enterprising entrepreneur developed the conglomerate that currently operated a group of companies - Great Lakes Assemblies, LLC, Gulf Shore Assemblies, LLC and Indiana Assemblies, LLC - providing manufacturing and supply chain management services for Toyota and other large car makers. On the strength of the auto industry and Vickers' laser beam focus on customer service, MAI has risen to the nation's fourth-largest black-owned industrial/service company with $1.2 billion in revenues. When Vickers spoke at the BLACK ENTERPRISE- Walmart 20/20 Vision Forum in Indianapolic last year, he shared with the audience that his company was able to reach the billion-dollar mark through mentorship and partnership from the BE 100s: Joseph B. Anderson, CEO of mechanical parts supplier TAG Holdings L.L.C. (No. 61 on the 2014 BE INDUSTRIAL/SERVICE list with $53 million in revenues) - his former employer.
