Conoco PhillipsVenco Richard G.From a personal standpoint, I was impressed with the repore the instructor had
with our class. He was extremely patient and enthusiastic about what he was trying to get across to us about operating and maintaining our crane. I was also very impressed with his knowledge of the electrical & mechanical workings of so many different types of cranes. He is truly a valuable resource to your company and to those he teaches.
Dietrich Industries Dominic L.I would highly recommend this course for our mechanics. Materials covered very
helpful
