Lion - Quotes

The instructor did an excellent job presenting a very dry subject; keeping everyone interested and making it enjoyable.

Marc Bugg

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!

Lion's online training is more comprehensive, has better slides, and is a superior training experience than what I would get from other trainers.

Our instructor was very dynamic and kept everyone's interest. Hazmat shipping can be a dry, complicated topic but I was engaged the entire time.

No comparison. Lion has the best RCRA training ever!!

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

This was the 1st instructor that has made the topic actually enjoyable and easy to follow and understand. Far better than the "other" training providers our company has attended!

The exercises in the DOT hazardous materials management course are especially helpful in evaluating your understanding of course information.

Morgan Bliss

Lion is at the top of the industry in compliance training. Course content and structure are updated frequently to make annual re-training enjoyable. I like that Lion has experts that I can contact for 1 year after the training.
