Medium/Heavy Diesel Service Technician 23-24

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.
