Jon McAlpin knew he was going to die of cancer. And if he was going to die, he figured “why wait?” It is, sadly, a not uncommon feeling among those who must face the disease. But Jon’s doctor said something that changed his outlook: “The end of your life doesn’t have to be the end of the world.” So Jon shares that reality, day in and day out, at the cancer center where he receives chemotherapy. As fellow patients enter, Jon welcomes them in while keeping their despair out. As the door greeter, he is perhaps the hospital’s most important employee. See despair turn to hope (and spread) in the clip below.
