CTAS logo

Cintas Corp

CTAS

Cintas has roots dating back to 1929, when the Farmer family cleaned and resold dirty rags to manufacturing plants in Ohio. The firm has expanded its business organically and through acquisitions, and today Cintas acts as a one-stop outsourcing partner for businesses. Cintas will design, manufacture, collect, and clean every employee uniform for a small weekly sum, taking on the upfront capital expense itself. At the same stop, Cintas can also replace soiled or depleted mats, mops, trash liners, towels, first aid supplies, fire extinguishers, and cleaning products. Businesses value an outsourcing partner like Cintas as it simplifies operations and leaves noncore tasks with high regulatory standards in the hands of professionals.
