A job fair at ASU Mid-South introduced Javier Soto to his future boss and career as a diesel technician for Paschall Truck Lines. Armed with two years of diesel tech classes and certification in air conditioning systems, he started at Paschall Truck Lines and has come to love the environment there and the people he works with.

Soto's day-to-day duties include providing basic maintenance on the trucks that come into the shop, repairing obvious damage and prepping the trade-in trucks. He also installs dash cameras and preps the new trucks that come into the shop before they are put out on the road. In order to succeed as a diesel technician, Soto says you should be accountable, willing to work with others, have great time management skills and have a knack for solving problems.

“They need to be precise with their work,” he says. “When someone leaves in that truck, it needs to be done correctly to prevent accidents.”
