A former professional athlete, Brian Sump had never turned a wrench in a shop before starting Denver-based Avalon Motorsports in 2007. But in the years since, he has used his business acumen and a detailed, process-based management philosophy to grow the German-specialty shop into what a number of industry consultants consider to be one of the best repair facilities in the industry. In 2015, Sump opened Urban Autocare, his second facility in Denver.
