Thomas Harris founded Dent Doctor in Little Rock, Arkansas, in 1986. This mobile and shop-based franchise provides paint-free dent repair to consumers, fleet companies and body shops. Dent Doctor, which began franchising in 1990, reported repairing over 350,000 vehicles in its first 14 years in business. Using tools and training exclusive to Dent Doctor, the backside of each dent is accessed and pressure is gently applied, removing the dent without harming the original finish. No dry ice, heat or suction is used. The dent will not "pop" back in later, and is a permanent repair.
