About Us


Established in 1985, AssemTech, Inc. (ATI) is a major contract manufacturer of a wide variety of assemblies. ATI serves its customers across the United States from its centrally-located, 12,000 ft2 headquarters in West Chicago, IL. It has also located sales offices and warehouses strategically around the U.S. to support its customers' requirements and offers offshore options for high-volume production that requires highly-competitive pricing.

The company originated in the garage of its founder, Chuck Hall, where his family assembled wire harnesses and cable assemblies for his then employer. Over the next few years their production rate increased to approximately 500 assemblies per week. In 1996, Chuck decided to make ATI his full-time job, and that previous employer remains a valued customer of ATI to this day.

ATI continues to grow at an accelerated rate, and it is evolving quickly to support that growth by adding key personnel, developing a strategic business plan, and moving to a new facility.
