PRIOR TO MSU
Stepteau was part of the 2025 indoor state championship team at St. Xavier High School. At that meet, he was a member of two victorious relays (4x200m and 4x400m) and placed 11th individually in the 55-meter hurdles. As a senior at the state outdoor meet, he finished eighth in both the 100m and the 300-meter hurdles, with the Tigers placing third in the final team standings. His top-seeded 4x100m relay did not finish its race at that competition. The previous year, the team won the second of back-to-back state crowns, while his 4x100m and 4x200m relays each captured second. That year, he was 10th in the 100m. His first state appearance came in 2023, when he placed 22nd in the triple jump. Regionally, Stepteau was a member of three relay title quartets as his Tiger squad captured every team championship from 2019-25. He also had a pair of individual runner-up finishes in the 100m and 300m hurdles.
