Founded in 1937 in Detroit as Dunham's Bait and Tackle. Dunham's stores were recently redesigned in a "race-track" floor plan, to give better segmentation and provide a more unique shopping experience in a "Superstore" format. In addition to traditional sporting goods, Dunham's stores now offer a full line of fashions and leisure clothing including blue jeans, shirts, sweaters, eyewear and athletic and casual footwear.

Dunham's store size ranges from 7,000 square feet to over 40,000 square feet, with the average Dunham's being in the 25,000-30,000 square foot range. To date, Dunham's has outlets throughout Michigan, Ohio, Indiana, Illinois, Iowa, Wisconsin, Pennsylvania, South Dakota, Minnesota, West Virginia and Maryland with plans for many new stores.
