Chicago’s list of the area’s top doctors was compiled by Castle Connolly Medical Ltd., which publishes a number of guides to the country’s outstanding physicians. Castle Connolly’s physician-led team of researchers follows a rigorous screening process to select top doctors on both the national and regional levels. Using mail and telephone surveys, researchers ask physicians and the medical leadership of area hospitals to identify exceptional, highly skilled doctors. They follow up with a careful screening of each doctor’s educational and professional credentials and experience before finally selecting those physicians most highly regarded by their peers.
