Everything you need to know about Cook County


My door is always open . . .

Cook County is responsible for providing essential services in the areas of public safety, public health, the court system, elections, tax assessment and appeals, recording deeds, and managing forest preserves. As an independent-minded member of the Board, I have worked hard to combine fiscal responsibility with social awareness. I am honored to serve the people of the 9th district, which includes: portions of the far northwest side of Chicago; Park Ridge, River Forest, Elmwood Park, Harwood Heights, Mount Prospect, Norridge, River Grove, Rosemont, and Schiller Park; portions of Arlington Heights, Melrose Park, Morton Grove, Niles, and Prospect Heights; and unincorporated Norwood Park, Maine, and Wheeling Townships.

Cook County's recent accomplishments.

Restoration & Redevelopment of the old Cook County Hospital

Redevelopment and restoration of the old Cook County Hospital--a Beaux Arts landmark--has been turned over to a private development team with the execution of a long-term lease. The developer, Civic Health Development Group, plans to invest $130 million of private dollars to transform the historic building into an anchor and catalyst for the Medical District and Near West Side. Historic restoration plans have been developed and refined by the world-renowned architecture firm of Skidmore, Owings & Merrill.     

The project, which has just broken ground, is being developed without the use of any Cook County public subsidies and/or funds. Construction will begin with interior, non-structural demolition, followed by restoration. Hyatt House/Hyatt Place will be the first tenants of the rehabilitated structure. Additional spaces include medical offices and retail. Stay tuned!
