Jack St. Ivany is an American professional ice hockey defenseman currently playing for the Pittsburgh Penguins in the National Hockey League (NHL). Born on July 22, 1999, in Manhattan Beach, California, he has built his career through a steady progression from youth hockey in Southern California to junior and collegiate competition before reaching the NHL. Selected 112th overall by the Philadelphia Flyers in the 2018 NHL Entry Draft, St. Ivany has developed into a dependable, right-shooting defenseman known for his size and hockey sense.
Early Life and Background
Jack St. Ivany grew up in Manhattan Beach, California, a coastal community in the Los Angeles area. Raised by his parents, Darin and Tricia, he grew up alongside a brother, Tucker, and a sister, Bella, in a supportive household that encouraged athletic development. The Southern California environment shaped his early years, though ice hockey opportunities required him to pursue organized programs beyond his hometown.
His first significant exposure to organized hockey came through the Los Angeles Jr. Kings, one of the region’s prominent youth development organizations. Playing in that program gave St. Ivany the foundation he needed to compete against top-tier talent and prepared him for the transition to higher-level junior hockey. The combination of family support and early competitive experience laid the groundwork for his future in the sport.

St. Ivany advanced to the United States Hockey League (USHL), joining the Sioux Falls Stampede for his junior career. The USHL is widely recognized as the top junior league in the United States and serves as a primary development pipeline for collegiate and professional hockey. His time with the Stampede allowed him to refine his defensive game and gain visibility in front of NHL scouts.
That visibility translated into a significant milestone when the Philadelphia Flyers selected him in the fourth round, 112th overall, of the 2018 NHL Entry Draft. Following the draft, St. Ivany committed to the collegiate route, a path valued for its blend of athletic and academic development. He also earned international recognition during this period, representing the United States at the 2019 World Junior Ice Hockey Championships.
