He has received multiple honors and awards for his work, including the President's Volunteer Service Award. In 2011, Hammond released his best-selling memoir, KaBOOM!

Born in Jerome, Idaho to a nursing home employee and a truck driver, Hammond is the seventh of eight children. Two years after Hammond's father abandoned the family, Hammond's mother had a breakdown and found herself unable to take care of the children, and they were sent as wards of the court to the Mooseheart Child City & School, a group home in Mooseheart, Illinois. During the 14 happy years he spent at the home before achieving the age of majority, he enjoyed his experiences on the group home's playground, and in his junior year at Ripon College first took part in helping to build a community playground, assisting the mother of a friend.
