USAF McNeal B.I like the exercises, it put things into perspective.
SZ Atlantic ErinInstructor was informative & was concerned that everyone understood. Thank
You!! (The Instructor) did a great job & enjoyed the class!
Lockheed Martin Mike Z.(What I liked most about the seminar was…) The tour of the facilities, and the
hands-on (the instructor) gave us in class.
Gerdau Ameristeel Mike M.(What I liked about the seminar was…) Learning about the mechanics as well as built in safe guards on cranes. I thoroughly enjoyed the course. I have operated
the mill crane off and on for 20 years. I learned more about cranes in the 2 1/2
day course than I have in previous years. Instructor did a great job.
Northrop Grumman Jeffery T.Very informative. The tour of P&H plants.
