Gierlich-Mitchell

What Gierlich-Mitchell does

Gierlich-Mitchell, Inc. is a manufacturers' representative firm founded in 1964 in California, serving municipal water and wastewater utilities across California and Nevada. The firm represents more than 30 leading equipment manufacturers — including Headworks International, Aqua-Aerobic Systems, EBARA Corporation, Hayward Gordon, Netzsch, Alfa Laval, Kaeser Compressor, Afton Pumps, and HFE Process — providing municipal customers with a portfolio spanning pumps (lift stations, submersible sewage, positive displacement, vertical turbine, chemical metering), process equipment (headworks, secondary treatment, MBR, tertiary filtration, disinfection, anaerobic digesters, blowers, dewatering), and supporting services.

The company's offerings extend beyond pure representation to include licensed professional engineering across mechanical, electrical, and biological design disciplines, Class A general contracting capabilities, and factory-authorized field services (start-up, preventative maintenance, vibration and alignment, installation certification, turnkey installation, warranty evaluation, and aftermarket parts). This integrated structure enables design-build and turnkey project delivery rather than simple equipment brokering.

Revenue is generated through commission-based manufacturers' representation on equipment sales, project-based fees for engineering design services, and service contracts for field work and maintenance. Go-to-market is exclusively field-based, with Technical Sales Engineers engaging directly with municipal utilities, consulting engineers, and contractors. Pricing is quote-based and project-specific with no public disclosure. The firm maintains five sales offices across California (Orange County, Sacramento, Fresno, Paso Robles, San Diego) in addition to its Brea headquarters, and is led by President Ryan McCloskey following the 2007 retirement of James G. Mitchell.
