Yontz began crew chiefing in the Xfinity Series midway through 2019 after the unexpected death of Nick Harrison, the crew chief of Kaulig Racing's No. 11 car driven by Justin Haley. He continued in that role in 2020 and 2021. When Haley moved up to Kaulig's new No. 31 car in the Cup Series in 2022, Yontz did not move up with him and he continued to crew chief the No. 11 car in the Xfinity Series, now driven by Daniel Hemric.

On September 9, 2022, it was announced that Yontz would be switching cars, moving from the No. 11 of Hemric to the No. 10 of Landon Cassill starting with the race at Kansas the next day. Both the No. 10 and No. 11 cars had struggled during the season compared to Kaulig's No. 16 car driven by A. J. Allmendinger and were close to the bottom of the playoff grid and in danger of falling out. (Even after the crew chief swap, Cassill's No. 10 car ended up missing the playoffs.) Jason Trinchere, who was the crew chief of Cassill's No. 10 car, switched cars with Yontz and became the crew chief for Hemric's No. 11 car.^[1] Yontz continued as crew chief of the No. 10 car in 2023 when it was driven by multiple drivers.

On December 19, 2023, Kaulig announced that Yontz would move from their No. 10 car to their No. 16 car in 2024 where he would crew chief A. J. Allmendinger, who returned to the Xfinity Series full-time after 1 year of running full-time in the Cup Series for the team.^[2]
