Mark began working in the cryogenic and liquid oxygen field for Airgas in their Portland Oregon facility. Mark was primarily responsible for keeping the mobile tanker fleet operational and troubleshooting problems with the tanks and cryogenic pumping systems.

Mark elected to go out on his own and offer his expertise to not only Airgas, but the other major Industrial Gas Suppliers located in the Pacific Northwest. He has assisted customers and their end users from Los Angeles to the US/Canadian border with evaluating their gas systems and the deployment, installation and maintenance of those systems.
