About Us

Home / About

In 2017, PSC acquired all of the outstanding ownership interests of HydroChem, combining both PSC and HydroChem to create HydroChemPSC. The combined company is led by executives from both organizations: Brad Clark, CEO of PSC, serves as HydroChemPSC’s CEO, President and member of the board. Gary Noto, HydroChem’s CEO, serves as the new company’s Vice Chairman and a member of the board.

Today, HydroChemPSC offers more to our customers than any other provider. Our collective national footprint, together with our vast array of services allow us to truly become that “one-stop shop” for our valued customers, who value service providers around whom they can consolidate services and thus reduce their contractor count and associated indirects.
