About Us

GMW began operations in 1982, as principals, Hilton Glavish, Barry MacKinnon and Ian Walker, from the defunct New Zealand company ANAC set up in the San Francisco Bay Area 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.

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.   read more
