Stephen was born at Camp Zama, Japan. He was raised mostly around Mana, Kekaha, Waimea valley and Makawelli on the island of Kaua‘i.
Growing up on Kaua‘i, Stephen claims his family never bought fish or poi. His favorite kalo includes Kaiʻulaʻula for its flavor and chewiness, and a keʻokeʻo kalo for its sweetness. Stephen is married to Tracy. They have three children and one grandchild. He enjoys "hanging out with the family," and volunteers coaching track & field with youth at the club and high school levels.
