After losing his 17-year-old son to cancer, Foster transformed his grief into a mission to help other families of children with the disease. In 1999 he created a foundation that relieves some of the financial burden families face when a parent must stop working to care for a child undergoing cancer treatment. The foundation has helped 250 families with grants of up to $2,500 each. When the worst happens, the foundation steps in to help with funeral costs.
