The mission of Castle Connolly Medical Ltd. is to help consumers find the best healthcare. To this end, we publish a variety of books including the “Top Doctors” series, the most popular of which is America’s Top Doctors®. The top doctors who are listed in our books and on this website’s directory were nominated by their peers in an extensive survey process of thousands of American doctors each year. These Top Doctors’ medical educations, training, hospital appointments, disciplinary histories – and much more – are screened by the Castle Connolly physician-led research team. Those doctors who are among the very best in their specialties and in their communities are selected for inclusion. Doctors do not and cannot pay to be included in any Castle Connolly Guide or online directory.
