Victories on the race track are tangible reminders of Pratt & Miller's success as a business enterprise. That success has come through sound planning and investment, as well as the expertise and hard work of the team they have assembled. Pratt & Miller Engineering & Fabrication was founded in 1989 by Gary Pratt and Jim Miller. Their aim was to create a world-class engineering company that could take automotive-based programs all the way from concept to reality. Since then, Pratt & Miller has become a respected industry leader, providing automotive and non-automotive clients with leading-edge engineering and low-volume manufacturing solutions. Pratt & Miller now is positioned among a very small group of North American companies, with proven capabilities to design, develop, build, race, and especially to win. It sounds exciting, but any racer will tell you that the glamour and excitement are the tip of the iceberg. The rest is hard work, and a lot of it, with time and quality demands that are intense. A nine-to-five job it most definitely is not. The green flag is going to drop on a certain time on a certain day ; delays and excuses simply aren't part of the deal. The skills and can-do attitude it takes to win at the upper levels of professional racing transfer well to non-racing automotive projects, too. That approach adds a vital element to Pratt & Miller's formula for success, whether a customer's goal is to win on the racetrack or in the automotive marketplace or both.
