Founded in Swanton in 1953 by Forrest and Roberta Cooley, Tri-County Block & Brick is a family-run manufacturer of concrete block and a supplier of masonry and building materials. Its block operation grew from an initial output of 2,000 units a day to 23,000 daily after a second on-site production facility was built in 1996. The Cooley family continues to run the business, serving Northwest Ohio and nearby areas with locally made block and a broad brick selection from partner manufacturers.
