Dennis Reinbold's grandfather "Pop" Dreyer is recognized as one of the early icons of open-wheel racing. After managing Duesenberg's factory racing efforts, Pop Dreyer became one of the most successful builders of midget, sprint and Indy cars.
In 1994, Reinbold joined Eric DeBord in fielding a BMW-supported entry in the IMSA Firestone Firehawk Road Racing Series. In 1999, Reinbold and DeBord joined forces again to form Dreyer & Reinbold Racing, which entered the Verizon IndyCar Series with driver Robbie Buhl.
In 2000, DeBord and Reinbold welcomed Buhl as a partner, and Buhl went on to win the 2000 season opener at Walt Disney World Speedway. In 2001, DeBord relinquished his ownership role. In 2004, Buhl took on a full-time ownership role after retiring as a driver.
Reinbold graduated from the University of Indianapolis with a bachelor's degree and earned an MBA from Indiana State University.
The team has a strong relationship with Racing for Kids, which has visited more than 20,000 children in hospitals in local race markets across the globe.
