Diesel InstructorMy name is Dave Escolas. I'm from Laramie, Wyoming, having graduated from high school here in 1979. I went to the University of Wyoming, then came to WyoTech and graduated from there in 1988. I worked as a Mobil Tech and Manager for Thermo King and Carrier, and have sailed the Pacific Ocean on Refrigerated Container ships. I helped build and worked the Bellagio in Las Vegas, had a 6 truck APU Refrigeration, ran a refrigeration trucking company with over 100 trailers and finally came back to teach at WyoTech in 2010. I left for a couple years in 2018 when the company was closing down and came back to continue teaching in 2020.
