Troy Stutzman

Sales and Business Development

Troy started with Indiana Diesel after seeing the need for additional diesel shops in his area.  As a haul and tow owner operator himself, he was constantly running into issues of timing in having his truck serviced, and wanted to change that for himself and others.  Often shops in the area were scheduled out weeks if not longer.  Troy’s goal is to partner with drivers, fleet owners and individuals to find them quick, affordable solutions for their maintenance and repair needs.  He understands the need to get fellow drivers back on the road quickly.
