Alsum Produce, Inc. started in 1973 as a one-person operation. Glen Alsum bought 50-pound and 100-pound bags of Wisconsin-grown potatoes and onions and repackaged them into 5-, 10-, and 15-pound bags. He then sold them to grocers in the Southern Wisconsin area. Business was good, and Glen doubled his warehouse space to just over 4,000 square feet. The product line was expanded in 1979 to include some of the more common fruits and vegetable items.
