Since Humana is a health insurance company, their business is all about fitness and nutrition, and they've chosen to promote golf as a way to keep healthy. At this year's Humana Challenge, 12,000 pedometers were given to attendees who walked 84,000,000 steps. Health screenings were available free of charge in their mobile wellness center and will continue to be so at several tour stops. Michael B. McCallister, Humana chairman and CEO, is a national trustee of The First Tee, the highest donor designation. Company employees serve as volunteers and board members of First Tee chapters in Chicago, Kansas City, Atlanta and Louisville. A grant from Humana provided funds for The First Tee of Greater Chicago's Healthy Habits Leadership Camp this past summer.
