Pangos is a third-generation Slovene Canadian as his paternal grandparents emigrated to Canada from the former Yugoslav Republic. He has a Slovenian passport. Like many young Canadians, Pangos played youth hockey. He had family connections to the game—an uncle played in the NHL, and a cousin was drafted by the Washington Capitals—but he did not like the sport as much as basketball. In any event, he had much deeper family links to that sport. His father Bill played basketball for the University of Toronto and finished his 26th season as the head women's basketball coach at York University in Toronto in 2013, his mother Patty played Canadian Interuniversity Sport basketball at McMaster University, and his sister Kayla played under their father at York. Growing up, Pangos' biggest inspiration was Steve Nash, a Canadian who developed into one of the NBA's top point guards and a two-time MVP. At training camps throughout his youth, Pangos paid special attention to stories about Nash; he recalled in a 2013 interview, "Someone would say, 'Steve Nash would make 500 shots a day.' I figured I had to make 500 shots a day." Although he played for various national and provincial youth squads, he frequently trained alone or with his father, as he found relatively little high-level competition in Ontario.
High school career
Pangos played for Dr. John M. Denison Secondary School in Newmarket, Ontario. In his senior season, he led Denison to the OFSAA Triple-A title game where he scored a game-high 26 points in a 69–64 loss to Anderson CVI.
College career
Pangos received offers from several NCAA Division I schools including Michigan, Temple, UNLV, Portland, and Cincinnati. Notably, he and Trey Burke were both offered scholarships to Michigan, but only on a first-come, first-served basis; Burke accepted first. Pangos opted for Gonzaga after receiving favorable reviews from Kelly Olynyk and his family; the Pangos and Olynyk families are longtime friends in the closely knit Canadian basketball community. In his second NCAA game against Washington State he scored 33 points and tied a school record with nine three-pointers made in an 89–81 victory. This game kicked off a stellar 2011-12 freshman season at Gonzaga, as Pangos led the team in many statistical categories including points, assists, steals, minutes played, 3-pointers made, and free throw percentage. He helped Gonzaga to a 13–3 record in the West Coast Conference, good enough for second place, and a 26–7 overall record. In the WCC semi-finals Pangos led Gonzaga by BYU in a 77–58 victory, scoring a game-high 30 points on 10–17 shooting. Pangos did not perform well in the 2012 West Coast Conference finals in a 78–74 overtime loss to Saint Mary's. Pangos shot just 3–18 from the field and 1–10 from three-point range. Gonzaga entered the 2012 NCAA Men's Basketball Tournament as a #7 seed. In his first NCAA tournament appearance, Pangos scored 13 points on 5–7 shooting and added 5 assists in a lop-sided 77–54 victory over West Virginia; however, Gonzaga would lose to #2-seeded Ohio State in the third round of the tournament 73–66. Pangos would score just 10 points on 3–13 shooting. On January 29, 2015, against Portland, Pangos broke Blake Stepp's school record of 288 made 3-pointers. As of March 11, 2015, Pangos currently has a school-record of 313 3-pointers, which is good enough for fifth place all-time in West Coast Conference men's basketball.
