About Us

The Illinois State Association of Counties (ISACo) is a statewide association whose mission is to empower county officials to provide excellent service to their residents. ISACo member counties are comprised of forward-thinking public servants who recognize that the challenges confronting county governments require new and innovative ideas, collaborative solutions and collective advocacy at the state and federal levels of government.

Counties are an essential partner in the federal, state and local governance relationship. To this end, ISACo represents county government as an institution and does not advocate on behalf of any specific county office.

ISACo provides education and training opportunities, peer-to-peer networking, shared resources and robust representation before policymakers at various levels of government. ISACo creates and connects county officials to these opportunities and successfully equips them to make counties ideal places to live, work and play. 

​ISACo is organized exclusively for non-profit purposes and will operate at all times in the manner contemplated by section 501(c)(4) of the Internal Revenue Code or by such other provisions of the Code that will assist ISACo to accomplish its non-profit purposes. ISACo is committed to the highest standard of ethical conduct and transparency in the pursuit of our mission.
