Jack St. Ivany Bio
Jack St. Ivany is an American professional ice hockey defenseman for the Pittsburgh Penguins of the National Hockey League (NHL). Born on July 22, 1999, in Manhattan Beach, California, he developed his game on the West Coast before advancing through some of the most respected amateur and college programs in the United States. Selected by the Philadelphia Flyers in the 2018 NHL Entry Draft, St. Ivany later signed with Pittsburgh and made his NHL debut during the 2023–24 season.
Early Life and Background
Jack St. Ivany was born in Manhattan Beach, California, a coastal community in the Los Angeles area known for producing athletes across many sports. He was raised by his parents, Darin and Tricia St. Ivany, alongside a brother named Tucker and a sister named Bella. Growing up in a region where ice hockey is less common than in northern states, St. Ivany found his way to the sport through the Los Angeles Jr. Kings, one of Southern California’s most established youth hockey organizations.
The Los Angeles Jr. Kings program gave St. Ivany his first structured exposure to competitive hockey and helped him develop the skating and defensive fundamentals that would define his game. His progression through the program caught the attention of junior scouts, and he eventually moved on to the United States Hockey League, the top amateur league for young players in the country. His time in Manhattan Beach and the surrounding South Bay area grounded him in a non-traditional hockey market, which shaped his work ethic and his willingness to adapt.
Path to Hockey
St. Ivany’s path to higher-level hockey continued with the Sioux Falls Stampede of the USHL, where he competed against many of the top draft-eligible players in North America. The USHL experience prepared him for the next step in his development and put him on the radar of National Hockey League scouts. In the 2018 NHL Entry Draft, the Philadelphia Flyers selected him in the fourth round, 112th overall.
Rather than turn professional immediately, St. Ivany chose the collegiate route to continue his growth as a player. He attended Yale University from 2018 to 2020 before transferring to Boston College, where he played from 2020 to 2022. During the 2021–22 season with the Eagles, he was recognized as a Hockey East Third-Team All-Star, an honor that highlighted his steady two-way play on the blue line. His four years of college hockey gave him time to mature physically and refine the defensive details of his position before entering the professional ranks.
Jack St. Ivany Career
Early Career (2018–2022)
St. Ivany’s early career was defined by his time in the USHL with the Sioux Falls Stampede and his four seasons of NCAA Division I hockey. With the Stampede, he played a regular shift on the back end and gained experience against older junior players, which helped him adjust to the pace of the professional game. His performance in the USHL contributed to his selection by the Philadelphia Flyers in 2018.
At Yale, St. Ivany adjusted to the speed and structure of the Eastern College Athletic Conference and continued to develop his defensive game. After two seasons with the Bulldogs, he transferred to Boston College, where he logged major minutes in Hockey East. The 2021–22 season was his most productive college year, as he earned Hockey East Third-Team All-Star honors and served as a trusted defenseman for the Eagles.
NHL Breakthrough (2022–2024)
Following the conclusion of his collegiate career, St. Ivany became an unrestricted free agent on August 15, 2022. Five days later, on August 20, 2022, he signed a two-year, entry-level contract with the Pittsburgh Penguins, officially beginning his professional career. He spent time in the American Hockey League adjusting to the pro game before earning his first NHL opportunity.
St. Ivany made his NHL debut on March 22, 2024, appearing for the Penguins in a game against the Dallas Stars. Less than two weeks later, on April 2, 2024, he recorded his first NHL point, assisting on a goal by Evgeni Malkin against the New Jersey Devils. The strong finish to the 2023–24 season led to a new commitment from Pittsburgh, and on May 21, 2024, the Penguins re-signed St. Ivany to a three-year contract extension.
Pittsburgh Penguins Era (2022–Present)
Since joining the Pittsburgh Penguins organization, St. Ivany has been viewed as a steady, defense-first defenseman with the size and skating ability to handle modern NHL matchups. He has continued to work on his game within the Penguins’ system, and his entry-level deal was followed by a longer-term agreement that signaled the organization’s belief in his trajectory. His role within the team has gradually expanded as he has gained experience at the highest level.
On October 2, 2025, the Penguins announced that St. Ivany had suffered a lower-body injury and would miss a minimum of six weeks. The injury interrupted his start to the 2025–26 season, but the team continued to count on him as part of its defensive group once he returned to full health.
Driving Style and Strengths
St. Ivany is recognized for his responsible, defense-first approach and his willingness to use his 191-centimeter frame to win battles along the boards and in front of the net. He plays a calm, positionally sound game and has shown a steady progression in his puck-moving skills since turning professional. His college background and time in the AHL have helped him build the patience and discipline that define his current style.
Notable Events and Milestones
Among the highlights of his young career, St. Ivany has represented the United States at the 2019 World Junior Ice Hockey Championships, his first major international tournament. His NHL debut in March 2024, his first NHL point against New Jersey, and his three-year contract extension later that spring stand as the most significant milestones of his professional journey so far.

Jack St. Ivany Family
Family Background and Racing Lineage
Jack St. Ivany was born to Darin and Tricia St. Ivany and raised alongside his brother, Tucker, and his sister, Bella. While his family is not a well-known hockey lineage, his parents supported his pursuit of the sport from a young age, even though they lived in a non-traditional market in Southern California.

2025 Season Performance
The 2025–26 season was poised to be an important step forward for St. Ivany within the Pittsburgh Penguins organization. Coming off a three-year contract extension signed in May 2024, he entered the year with a clearer role on the blue line and an opportunity to build on his late-season NHL debut from 2023–24. Early in the campaign, however, the Penguins announced on October 2, 2025, that he had suffered a lower-body injury expected to keep him out for a minimum of six weeks.
The injury interrupted his rhythm at the start of the season, but Pittsburgh’s investment in his long-term development suggested he remained part of the team’s plans. Once healthy, St. Ivany was expected to return to a defense group that valued his size, his responsible play, and his continued growth as a puck-mover. The 2025–26 season, regardless of the setback, is serving as a key year in his transition from prospect to established NHL defenseman.
Looking ahead, St. Ivany’s combination of college pedigree, international experience, and professional opportunity with the Penguins positions him as a player to watch as he continues to log NHL minutes and refine his game at the highest level.
