Dr. David M. Mannino, chair of the department of preventive medicine and environmental health at the University of Kentucky College of Public Health and a professor of medicine in the division of pulmonary, critical care, and sleep medicine, has been recognized as the number one leading expert in the United States for Chronic Obstructive Pulmonary Disease. As part of its ongoing program to highlight excellence in healthcare and in conjunction with Chronic Obstructive Pulmonary Disease (COPD) Awareness Month, Expertscape News released the inaugural rankings for both U.S. doctors and institutions Nov. 19, 2013, of which Dr. Mannino was awarded the number one position of expertise. “These rankings reinforce what Dr. Mannino's University of Kentucky colleagues already knew," said Dean Stephen Wyatt. “David Mannino is an amazing campus, national, and international resource.”
