His primary focus, health care, is the subject of Sick: The Untold Story of America's Health Care Crisis - and the People Who Pay the Price, a book that serves as the definitive guide to the forthcoming debate over whether, and how, to reform the U.S. health insurance system. Sick was named a finalist for the New York Public Library's Helen Bernstein Book Award for Excellence in Journalism. Widely respected for his engaging writing style and ability to make complex issues seem simple, Cohn is a lively speaker who particularly relishes opportunities to make a case for his generally (but not always) liberal views to more conservative audiences. Since the publication of Sick he has become a widely sought after speaker and has given talks to health care companies and organizations and activist groups across the country.
