Also to be honored will be Greg Wasson, former president and c.e.o. of Walgreens. The honorees will be presented with the award at G.M.A.’s Leadership Forum in August at The Broadmoor in Colorado Springs, Colo.

“Gary Rodkin, Greg Wasson and George Deese are prime examples of leaders in the consumer packaged goods industry who are committed to strengthening our industry and who are making a difference in the everyday lives of consumers,” said Pamela G.
