About GMW


GMW began operations in 1982 in Redwood City, California. Hilton Glavish, Barry MacKinnon and Ian Walker, from the defunct New Zealand company ANAC, came to the US to support their existing North American customers. The company quickly moved from solely Lab Electromagnets into instrumentation, getting into the Magnetic Resonance Imaging (MRI) business with the founding of Metrolab Technology in the mid 80’s. Accelerator Physics and MRI drove growth throughout the 80’s and into the 90’s, with the Superconducting Supercollider (SSC) cancellation in 1993 allowing the company to further diversify into additional markets. GMW moved to our current location in San Carlos in 1991, and has expanded our Industrial Road facility three times since, now having 13,000 square feet and adding state-of-the art measuring equipment in magnetic field and electric current.

Current Transducers, originally developed for Accelerator Magnet Power Supplies, diversified into MRI Gradient Amplifiers, Power Electronics, and Hybrid-Electric Drive Test & Measurement.

Today, GMW are 20 people with co-founder Ian Walker now entering his 37th year at GMW and continuing to offer a very high level of support to our customers. Two of the current officers, Brian Richter and Lalo Guitron joined within months of one another in 1998. Our 3rd officer, Ben Hartzell joined in 2011. GMW is 100% employee owned with 7 shareholders all full-time at GMW. We are at heart a company that exists to solve customer problems, with our core expertise being in magnetics. This magnetics expertise drives our focus in sensors, transducers and test and measurement instrumentation.  Key industries remain Particle Accelerators and MRI, with Electric Vehicles, Power Electronics, Spintronics, Materials Research, Oil & Gas all contributing.

Quality and Calibration

GMW expanded in-house NIST-Traceable calibration for MRI instrumentation to Current Transducers. ISO-9001 was obtained in 2014 and is audited twice annually. Accredited Calibration was added in 2018 and its scope continues to expand.

ISO 9001:2015 Certification

GMW achieved ISO 9001:2008 Certification in October 2014, and updated our Certification to 9001:2015 in October 2017. Certification was conducted by Perry Johnson Registrars, whose accreditations include ANAB (ANSI-ASQ National Accreditation Board) and UKAS (United Kingdom Accreditation Service).

ISO 9001:2015 Certification is an internationally recognized set of standards for quality assurance, quality management and continuous improvement. The standards represent best practices, policies and procedures to ensure that GMW will continue to consistently meet our customers’ needs for superior products and technical support.

ISO/IEC 17025:2005 Accreditation

GMW Associates achieved ISO/IEC 17025:2005 Accreditation in February 2018 for technical competence in the field of Calibration. This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system. The ISO/IEC 17025:2005 standard is an internationally recognized standard that specifies the general requirements for the competence to carry out tests and/or calibrations, including sampling.

Accreditation was conducted by A2LA, the only independent, 501(c)3, non-profit, internationally-recognized accreditation body in the United States that offers a full range of comprehensive laboratory and laboratory-related accreditation services and training.
