We are only as good as our people. Ron Feltz, Director of Operations, is proud of the shop crew he’s helped assemble. Their expertise includes everything from diesel mechanics, cooling and refrigeration systems, brake systems, welding and fabricating all types of metals; cargo tank inspection, testing, and repairs.

Everyone in the shop has studied and worked to earn their industry qualifications and certifications. They maintain certifications and receive on-going training through Tulsa Trailer’s continuing education program. Employee and workforce development is one of Tulsa Trailer’s core values.
