Kingsbury's background is not in competitive curling, though he has curled since high school, and has played in leagues at the Manotick and Ottawa Curling Clubs. He was a competitive golfer in university, where he became interested in sporting performance under pressure,[2] conducting academic research in the sport.[3] Kingsbury played in the Canadian University/College golf championships in 2004, where he missed a putt by six inches from just 2 ½ feet from the cup. The nerves he felt at this moment sparked his interest in sport psychology.[4]
He joined the Rachel Homan rink in 2015 to help with their mental preparation while he was a PhD candidate in clinical psychology[5] at the University of Ottawa.[6] He began to be associated with the team after his business partner introduced him to Curling Canada's high-performance director Gerry Peckham. He became their head coach in 2016 after their previous coach, Marcel Rocque took a position with the Chinese national program.[3] As coach, he was charged with improving the team's mental strength, and data collection.[6] With Kingsbury, the team won the 2017 Scotties Tournament of Hearts, the 2017 World Women's Curling Championship, and the 2017 Canadian Olympic Curling Trials. The latter earned the team a spot at the 2018 Winter Olympics, where they finished sixth. He left the team in 2018.[5]
After leaving the Homan team, Kingsbury expected to take some time off from curling. However, he was asked to join the Brad Jacobs rink as their coach for the 2018–19 season to help the team with the "psychological ... and mental aspect of the game".[7] He coached the team at the 2019 Tim Hortons Brier where they won a bronze medal.[1]
After a season with Jacobs, Kingsbury joined the Matt Dunstone rink as their coach for the 2019–20 season.[8] Team Dunstone won a silver medal at the 2023 Brier and bronze medals at the 2020 and 2021 Briers with Kingsbury as coach. At the 2025 Brier, Kingsbury was the team's alternate player.[1] As their alternate, Kingsbury threw two rocks, scoring a 100 per cent on both of them.[9] At the Brier, the team went on to win silver, losing in the final to the Brad Jacobs Alberta team.
