About Us

The Crew


​​CDDA was started to provide quality demolition derby promotions from the perspective of a driver. Chad Markley has built, drove, and won at all levels of demolition derby shows for over 25 years across Kansas, the midwest, and nation-wide. The combination of a promoter and a winning driver has garnered the respect of fair boards, promoters, fabricators, and other demolition derby drivers.
