After almost two decades competing on the ice, Lazar moved to a coaching role to begin the 2016-2017 curling season. Lazar joined Team Stopera, a newly formed group within the US Junior High Performance Program. The team consisted of Andrew Stopera at skip, Luc Violette at third, Ben Richardson at second, and Graem Fenson at lead. The team had instant success under Lazar's tutelage, winning the 2017 Junior Nationals and earning the silver medal at the 2017 Worlds. Lazar remained with the team in its subsequent two seasons, repeating as a national champion coach in both 2018 and 2019. The team never experienced the same success at the worlds as it did in its first season, finishing 4th in 2018 and 5th in 2019. Lazar also coached the team to an 8th place finish at the 2019 Winter World University Games.
