Medium/Heavy Diesel Service Technician

Diesel technology affects far more than just trucks. Diesel technology includes heavy equipment, oil exploration and extraction, marine industries, the national gas industry, and big trucks.

As a student at Francis Tuttle's Diesel Technology training center, you will prepare to work on some of the top equipment in the industry. Learning is hands-on and students have the opportunity to work on diesel equipment from a variety of Francis Tuttle's partners such as Cummins, Caterpillar, Freightliner, International, and Volvo.

Training is evaluated through intense studies in the classroom and hands-on evaluations in the lab.
