As the Technical Sales Engineer for MAHLE, I am fortunate to work with many diesel engine businesses. When I had a dealership ruin my personal diesel engine, I had the truck shipped to Cass. I could not be more pleased with Choate Engineering. Cass is exceptionally knowledgeable on diesel engines including theories of operation and choosing correct parts for the engine’s planned usage. He is extremely professional and helpful to answer all my questions. Cass is an honest man with high integrity. I highly recommend Choate Engineering.
