About Us


A Tradition of Excellence

With a 70-year tradition in excellence, we’re proud of the reputation we’ve established as a service provider and business partner. But we’re not stopping there. Acceleration is the name of our game, and we’re constantly transforming our business to fuel your needs. We’ve bolstered our teams by hiring the best in the industry, expanded our technician training to cover the latest technologies, and streamlined our work flow to get you in, out, and back to work.

And while we’re big enough to take care of you, Western Branch Diesel is small enough to really know you. We are dedicated to delivering superior customer service, and that’s a promise.

From the sales office to the service center floor, our goal is to get you there — wherever your job takes you.
