Wisdom built component by component

Founded in 1956 by WWII veteran Jim Peacock, the company began with simple manufacturing jobs like making bushings for local businesses.

Tom Peacock started at age 12, learning the technical and relational sides of the business—from shop floor skills to supplier and customer relationships—directly from his father.

The building has two windows with metal awnings, a door, and wooden pallets leaning against the wall. Two men standing indoors in front of a wall with a chart and a door labeled 'WAR ROOM'. The older man on the left wears glasses and a light-colored short-sleeve shirt; the man on the right, with a mustache, holds a wooden plaque.
