Diesel InstructorMy name is Matthew "Big Bear" Barnes. I am a 3-year graduate of WyoTech. I have welded for 13+ years and I am an almost 9-year Army veteran, having worked on just about everything that came into my maintenance bay. After graduating WyoTech, I went to work for mom and pops shops and local ranchers, with a little time at T&T motorsports. I ended up at Tungsten Parts in Wyoming, where I was lead and head of maintenance for almost three years.
