Established in 1973, Thompson Industries


In 1973, Ed Thompson Sr. left his job managing the tool room at a large manufacturing company to pursue his dream of opening his own machine shop.

He purchased a small building located in the town of Genoa, IL and began producing parts with just a couple of machines and his own two hands.

As business continued to grow as a result of the high quality service, Ed Sr. added more machines and more staff in order to handle the additional business.

In 1988, Ed Thompson Jr. (Ted) joined Ed Sr. and the 2 grew the business together. Following Ed Sr.’s retirement in 2001, Ted assumed the role of president and has taken the business to new levels.

The company has since built in a 22,000 SF facility in their home town of Sycamore, IL. Thompson Industries continues to add talented staff as well as the latest in machine technology in order to accommodate the ever changing customer demand.

In the Summer of 2026 we plan on expanding our capabilities into a new 80,000 SF state of the art manufacturing facility.
