About Cerris Systems
Cerris Systems began in Kansas City in 1932 as Midwest Plumbing & Heating, spent decades as MMC Contractors, and took its current name in a 2024 rebrand. The national mechanical (MEP) contractor has been 100% employee-owned through an ESOP since 2002 and operates from roughly a dozen offices, with its founding-city hub still in Kansas City. Ranked among ENR's top mechanical and sheet-metal specialty contractors, its capabilities run from preconstruction and prefabrication through building automation and 24-hour service, on work spanning healthcare, mission critical, power, and entertainment projects.
