McCarthy's Mark Shimko Earns Elite OTR Training Certification

McCarthy Tire Service Inc.'s Mark Shimko, the company's off-the-road tire and commercial safety trainer, has earned the highest level of certification in the OTR tire industry. And he's one of only eight in the world to do so. Shimko earned his 400-Level Earthmover Instructor certification from the Tire Industry Association (TIA). This designation allows Shimko to instruct and certify McCarthy Tire Service OTR tire professionals as certified earthmover technicians (Level 300) through TIA.

“We are very proud of Mark for the hard work and dedication it took to reach this certification level,” says company president John McCarthy Jr. “As a family company, it is vitally important to us that every one of our associates goes home to their loved ones safe and sound. We want to ensure that our associates receive the very best safety training available, which is why we are the first commercial tire dealer in the US with an advanced-level OTR trainer on staff.”

Shimko works from McCarthy's corporate office in Wilkes-Barre, Pa. He handles new hire and refresher training for the OTR and commercial truck service operations.

He has 21 years of experience in OTR and commercial truck tire service. He completed TIA’s basic Earthmover Tire Service (ETS) program and Michelin’s Earthmover Tire Service Technician seminar, and he recently attained his advanced 300-level Earthmover Tire Service (ETS) certification through TIA and Michelin Earthmover. Shimko also holds certifications for the Mine Safety and Health Administration (MSHA) Part 48 and Part 46 safety training, and is certified in Red Cross first aid, CPR, and AED.

Prior to joining McCarthy, Shimko served in the U.S. Navy for 10 years.

McCarthy holds the No. 22 spot on the Modern Tire Dealer 100, and is the seventh-largest commercial tire dealer in the U.S.
