Always Training To Stay the Experts In Our Field

Due to the recent rise in the Covid-19 Delta variant, effective immediately all students attending in-person training will be required to be fully vaccinated and have had their final vaccination two weeks prior to the first day of class.

After an enrollment is made, you will receive an enrollment confirmation. You will also be provided a Covid vaccination verification form to be filled out and sent back to the training department prior to the first day of class.


To be the best, you must train to be the best. That’s why the Clarke Power Services team believes in extensive continuing education that turns out true experts on a variety of makes and models.

Our high-tech training centers in St. Louis, MO, and Knoxville, TN, offer Clarke Power Services technicians and customers the hands-on opportunity to work on Allison Transmissions, Detroit Diesel engines and Mercedes-Benz engines. In addition, Clarke Power Services trainers can tailor classes to meet the specific requirements of our customers.
