Tierney Signs was first started in 1978 by John J. Tierney. It was operated out of a small brick garage behind the house.  As the business grew, so did the need for space, and a second larger garage was built next to the first.  The business continued to grow, and eventually the shop was moved to grass lake rd. in Antioch, IL.  Things continued to progress, the family moved out of the house where the previous shop was operated, and so the business moved back to it’s previous location, but now it occupies the bottom floor of the house (and the attached garage, and the two previously mentioned garages.) At this current time, it is unknown how much further Tierney Signs Incorporated will continue to expand, but the upstairs tenant should probably be on the alert for encroaching sign equipment.
