An Indianapolis native, Dennis Reinbold grew up less than a mile from the Indianapolis Motor Speedway amidst a family deeply entwined in the city's automotive heritage. After graduating from Cascade High School, he received his B.S. in Business from the University of Indianapolis, followed by earning his MBA from Indiana State University, and currently resides in Indianapolis.

Reinbold's grandfather, the legendary "Pop" Dreyer, led the Duesenberg Auto Factory's racing efforts, and later became a National Champion builder of midgets, sprint cars, and early Indy-style race cars. Having spent his entire career in the automotive industry, Reinbold is the principal of Indianapolis-based Dreyer & Reinbold, Inc. His numerous dealership include brands such as BMW, Infiniti, Maserati, Mini-Cooper, Subaru, and Volkswagen. After racing a variety of cars himself, Reinbold's inherited racing passion led him to found Dreyer and Reinbold Racing in the Indy Racing League in 1999, which he now co-owns with former driver Robbie Buhl.

Reinbold has served on the International Infiniti Product Committee, was Chairman of the Infiniti Dealer Advisory Board, and has served as President of the Indianapolis Auto Trade Association, and Indiana State Auto Association. He is a former member of the 500 Festival Board of Directors and was a former pitcher for the University of Indianapolis, participating in the College World Series. Reinbold resides in Carmel with his wife Jennifer and sons Derek and Graham.

After 21 years as a professional driver, Indy Lights champion and IndyCar Series race winner, Robbie Buhl now focuses on his role as co-owner of the Dreyer & Reinbold team. Buhl spent six seasons as the driver of the #24 Dreyer & Reinbold Racing (DRR) entry in the IndyCar Series.  Buhl's successes include national championships in the Indy Lights Series (1992) and the Barber Saab Pro Series (1989). He has scored two victories in the IndyCar Series (Orlando, 2000 and New Hampshire, 1997), and won the Rolex 24 Hours at Daytona in 1993. His total IndyCar Series career winnings are more than $4 million.

Robbie earned a BA in business administration and economics from New England College, where he also received NCAA All-Division III honors in lacrosse. His competitive instincts began early, racing dirt bikes, go-karts, and snowmobiles against his three brothers. Buhl still skates with the Grosse Pointe Old Devils Hockey Club whenever he visits his hometown of Detroit.

Off the track, Buhl has spent thousands of hours as the national spokesperson for "Racing for Kids," a national youth charitable foundation. On behalf of "Racing for Kids," Robbie has visited more than 20,000 children in over 400 hospitals worldwide, and raised nearly $5 million for local children's health initiatives. Both the U.S. Congress and his alma mater have recognized Buhl's charitable efforts. For 2011, Buhl and Racing for Kids celebrates the organization's 2nd birthday and 12th season associated with Dreyer & Reinbold Racing. Buhl resides in Cleveland with his wife, Becky, and daughters Carly and Quinn.
