Our service department offers full-service support on everything we sell, a complete line of parts, and warranty administration. Our commitment is to correct the problem right the first time and keep your buses on the road and operating safely.

Factory Trained Technicians

All our technicians and service support staff are factory trained and authorized to perform any and all repairs on the products we sell.  They are the bus experts.  Our primary focus is on buses and we are very good at it.  Our staff is required to attend continuing education to keep up with the ever changing world of buses.

Onsite Training

Employees that are knowledgeable and capable in their skills are more productive, safer, motivated and efficient.  Our courses are developed to meet the highest learning standards.  We do this by providing solid foundational knowledge and extensive hands on application.  We provide training either at your location or ours.  Classes are tailored to meet your technician’s level of training needs.
