His parents, Yule and Ruth, migrated to the United States to escape the effects of World War II. He was born the oldest male of eight children.
A range-rider, it has been his job to protect his brother's cattle against a range of Alaskan wildlife, from bears to wolves and coyotes.
He and his wife Bonnie have four children, Shane, Jewel, Atz Lee, and Nikos.
His younger brother, Otto Kilcher, appears alongside him on Alaska: The Last Frontier.
