Pionk was born on July 29, 1995, in Omaha, Nebraska,[2] to parents Karen and Scott Pionk.[3] His father played baseball for Proctor High School and the University of Wisconsin–Superior before coaching ice hockey at the youth level and for the United States Hockey League (USHL).[4] Pionk was raised in Hermantown, Minnesota, a suburb of Duluth, where his father built a baseball diamond and an ice hockey rink for Pionk and his friends to practice.[5] All five Pionk brothers played baseball and ice hockey as children, and after school they would play two-on-two hockey in this backyard ice rink.[6] In his adolescence, Pionk played with future National Hockey League (NHL) player Dylan Samberg on youth teams and for Hermantown High School.[7] Pionk and his brothers also created an annual pick-up hockey tradition with fellow brothers Travis and Cole Koepke. They referred to this annual tournament as the Holiday Cup.[8] In his final season for Hermantown, Pionk scored 14 goals and 29 points in 25 games.[9]

The Sioux City Musketeers selected Pionk in the fifth round, 66th overall, of the 2012 USHL Draft.[10] Immediately after taking Hermantown to a state championship title in 2013, Pionk left the school to begin his junior ice hockey career in Sioux City.[11][12] He played 12 games for the Musketeers during their 2012–13 season, recording one goal and six points in the process.[9] The next season, he recorded two goals and 23 points in 54 regular season games for the Musketeers.[12] Sioux City advanced to the Western Conference Finals of the 2014 USHL championships, where they were swept by the Waterloo Black Hawks.[13] Overlooked in the 2014 NHL Draft, Pionk served as captain of the Musketeers for the 2014–15 season.[14] With seven goals and 41 assists in 53 regular season games, Pionk led all USHL defensemen in scoring, and he was named the USHL Defenseman of the Year at the end of the season.[10] The Musketeers were eliminated by the Sioux Falls Stampede in a five-game Western Conference Semifinal series that postseason.[15] In 119 career games for Sioux City, Pionk recorded 10 goals, 77 points, a +44 plus–minus rating, and 199 penalty minutes.[16]
