Meet the team

Steven Paul, the sole owner of TDT Vehicle Inspection Appraisal Services (TDT Vehicle Inspection Services, INC) has been inspecting, repairing and diagnosing vehicles from an early age of 10 years old.  Steven grew up in a family of automobile enthusiast ranging from his grandfather on his mother's side to his father and uncles.  Steven often visited the local race track where he fell in love with the sport of dirt track racing and befriended a team who ran an auto body shop.  From that day forward Steven worked at the shop after school and on weekends working on the race car, pulling dents, straightening frames, performing mechanical repairs and sweeping floors.  When Steven turned 19 he joined the United States Army as a heavy equipment vehicle technician where he learned the art and skills required to diagnose engines, transmissions, and other major assemblies and would disassemble them and rebuild them and replace them as required.  After three overseas deployments and six years of service to our great nation, Steven joined the private sector where he worked in several maintenance facilities on heavy trucks, automobiles and construction equipment.  Many years later Steven went out on his own and founded Test Drive Technologies Vehicle Inspection Appraisal Services which has been in operation since 2009.
