The Cooperative State Research, Education, and Extension Service (CSREES) is an agency within the U.S. Department of Agriculture (USDA), part of the executive branch of the federal government. The 1994 Department Reorganization Act, passed by Congress, created CSREES by combining the former Cooperative State Research Service and the Extension Service into a single agency. Colien Hefferan currently serves as the agency's Administrator.
