John cleans up other people’s messes. The big scary messes. Asbestos, mold, you name it and John has seen it and remediated it.  Not only does John help GHP, Inc. clients clean up, he also trains our clients on how to avoid those messes in the first place. In fact, that’s his favorite part of the job – getting challenging questions from his students.

But John isn’t all work and no play. Hanging out in our Denver office has its perks for the avid fly fisherman and skier. Although John has a very serious job he’s always trying to lighten the mood and even incorporates a little comedy into his training programs. After all, his favorite quote is, “Don’t take life too seriously, you’ll never get out of it alive.”
