Robert "Robbie Redneck" Christlieb has a tenacious and sometimes stubborn personality. After working at an acrylic company in Colorado, he decided to move to Las Vegas. Desiring to continue in his field, he ran across ATM and called Wayde to see if he was hiring. That was 14 years ago. It was a perfect match, and he truly couldn't picture himself anywhere else.

Clearly the most serious of the crew, Robert is responsible for putting together the ins and outs of each tank. But don't let the straw hat and easy-going attitude fool you; he is very particular and extremely committed to perfection, often residing in a trailer home right outside the warehouse throughout the week to make sure things turn out right. Wayde and Brett have affectionately nicknamed him "Redneck". His unforgettable demeanor makes him an easy target for the ATM crew's day-to-day joking, but at the end of the day they unanimously agree he's the best builder they have and trust him to execute the job.
