I like Lion's workshops the best because they really dig into the information you need to have when you leave the workshop.

Tom Bush, Jr.

EHS Manager

You blew the doors off the competition!

Stephen Bieschke

Facilities Manager

I tried other environmental training providers, but they were all sub-standard compared to Lion. I will not stray from Lion again!

Sara Sills

Environmental Specialist

I was able to present my scenario to the instructor and worked thru the regulations together. In the past, I attended another training firm's classes. Now, I have no intention of leaving Lion!

Diana Joyner

Senior Environmental Engineer

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

Robert Brenner

District Environmental Manager

As always, Lion never disappoints

Paul Resley

The instructor created a great learning environment.

Avinash Thummadi

CAD & Environmental Manager

One of the best trainings I have ever received!

Brandon Morfin

EH&S Manager

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

Mary Sue Michon

Environmental Administrator

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