Worthington Scott C.Small and casual course setting. Ability to take things apart in the lab and see how they work.
Gerdau Ameristeel Clifford H.(What I liked about the seminar was…) Technical information about the subject.
US Synthetic Corp. Ben J.What I liked most about the seminar was...) Training facility
National OilwellVarco Bennie C.It was enlightening.
Gerdau Ameristeel Wayne J.(What I liked about the seminar was….) How much knowledge that instructor
shared. Instructor did a great job. He has a great deal of knowledge about cranes and the components. He (did) good on his presentations and should be recommended. This was one of the better class that I've taken with a good instructor.
