In 1988, a new outreach program was launched at the Institute of Medicine. Through the generosity of the Richard and Hinda Rosenthal Foundation, a lecture series was established to bring to greater attention some of the critical health policy issues facing our nation today. Each year one or more experts present their views and insights on a major health topic, and the Institute of Medicine later publishes these lectures for the benefit of a wider audience.

The Rosenthal Lectures have attracted an enthusiastic following among health policy researchers and decision makers in Washington, D.C., and across the country. The lectures typically engender a lively and productive dialogue. In this volume, we are proud to present the remarks of the 2007 Rosenthal Lecturers—Drs. Kevin Grumbach, Fitzhugh Mullan, and Marla E. Salmon—who spoke on "Transforming Today's Health Workforce to Meet Tomorrow's Demands."
