He grew up in Murdo, South Dakota and graduated from Jones County High School in 1980. Jay joined Old Dutch in 2003, where he was known for his hard work and friendly demeanor.

Jay married the love of his life, Deb (Hirsch) Penticoff on September 21, 1991. Together, they welcomed their cherished son, Dawson on October 8, 1999. Jay and Deb treasured every opportunity to spend time traveling to watch baseball games, camping, and supporting Dawson from t-ball through college baseball. Deb is a devoted Chicago Cubs fan and Jay loved the Colorado Rockies, creating some memorable matchups.
