Excellent. I learned more in two days with Lion than at a 5-day program I took with another provider.

Having the tutorial buttons for additional information was extremely beneficial.

Sharon Ziemek

EHS Manager

The instructor took a rather drab set of topics and brought them to life with realistic real-life examples.

Tom Berndt

HSE Coordinator

Well designed and thorough program. Excellent summary of requirements with references. Inclusion of regulations in hard copy form, as well as full electronic with state pertinent regulations included is a great bonus!

Oscar Fisher

EHS Manager

The instructor was probably the best I ever had! He made the class enjoyable, was humorous at times, and very knowledgeable.
