Castle Connolly Medical Ltd. is a healthcare research and information company founded in 1991 by a former medical college board chairman and president to help guide consumers to America’s top doctors and top hospitals. Castle Connolly’s established nomination survey, research, screening and selection process, under the direction of an M.D., involves many hundreds of thousands of physicians as well as academic medical centers, specialty hospitals and regional and community hospitals all across the nation. Castle Connolly’s physician-led team of researchers follows a rigorous screening process to select top doctors on both the national and regional levels. Its online nominations process—located at www.castleconnolly.com/nominations—is open to all licensed physicians in America, who are able to nominate physicians in any medical specialty and in any part of the country, as well as indicate whether the nominated physician is, in their opinion, among the best in their region in their medical specialty or among the best in the nation in their medical specialty. Careful screening of doctors’ educational and professional experience is essential before final selection is made among those physicians most highly regarded by their peers.
