ABOUT US

Since our beginning in 1950, DuBois-Cooper Associates has delivered high-quality equipment to our customers in Michigan. Duke DuBois and Jack Cooper founded DuBois-Cooper Associates in 1950 as a manufacturer representative company in the water and wastewater treatment industry. The leadership of the company transitioned to Jim Cooper (Jack’s son) and Barry Simescu in 1984 for the continued technical expertise and support in offering our represented equipment. Today, the DuBois-Cooper team is led by Joseph Moore where the founding principles continue to guide the company – offer quality industry-leading equipment, customer service, honesty and stewardship of water resources. We specialize in engineered solutions to our customers infrastructure needs with our goal of Protecting Michigan’s Water.
