William Heisel is an investigative reporter at the Orange County Register specializing in health and welfare issues. His work has been a finalist twice for the Pulitzer Prize since 2004 and has won two Loeb Awards. He also has won the Sigma Delta Chi Award from the Society of Professional Journalists for public service reporting. A graduate of the University of Montana, Heisel began his career at his home town paper, the Great Falls Tribune, and later worked for the Associated Press and newspapers in Montana and Washington state. He was one of the lead reporters on the Register's "Body Brokers" series, which exposed the money being made from human tissue donations. His stories about the Medical Board in California led to changes in the composition of the board and ultimately led to an Orange County doctor surrendering his license.
