liz-aaronAaron Muller, President

With Paul Whittier, Aaron founded Mr. Truck Wash in 2008. Previously he had owned and operated a mobile truck wash company from 1992 and then sold it in 2000. His passion for the industry never subsided and after watching the industry lack growth in practices he witnessed a huge need for quality washing and legitimate waste water management. Aaron helped develop innovative, proprietary equipment that recaptures and recycles water during the onsite truck washing process. Aaron sees green business as a calling. An entrepreneur since the age of 18, he zealously merges the practical and idealistic at MTW.

Paul co-founded Mr Truck Wash with Aaron Muller in 2008 with the aim of running a full-service truck washing company that could guarantee its clients that by using it, they would be in compliance with all applicable environmental regulations. Already a successful entrepreneur, Paul helped fill a hole in the Pacific Northwest’s market with the start of MTW. Proud of the company’s eco-friendly record, Paul helps generate new business and ensures that all aspects of MTW remain on the cutting edge of green cleaning technology.
