Born in Moscow, Golesh moved to the United States as a child, growing up in Brooklyn, New York and Dublin, Ohio.
Golesh was hired as the tight ends coach and recruiting coordinator at Iowa State in 2016 under Matt Campbell, who he worked with at Toledo.
Golesh mentored all-conference performers at tight end in 2017, 2018 and 2019, as the Cyclones recorded a pair of 8–5 seasons and back-to-back bowl berths in 2017 and 2018.
Sophomore tight end starter Charlie Kolar caught 51 passes for 697 yards (most yards all-time by a Cyclone tight end in a season) and seven touchdowns, helping him earn second-team All-America honors from Pro Football Focus and first-team All-Big 12 recognition, as well as first-team Academic All-America notice.
The tight production helped Iowa State rank 11th nationally and second in the Big 12 in passing offense at 311.3 yards per game.
