On 16 November 2022, Offerhaus signed with fellow Tweede Divisie club Quick Boys, set to join them at the start of the 2023–24 season.[6][7] Offerhaus made his debut for Quick Boys on 19 August 2023, in the season's opening match, starting in a 3–1 away victory over De Treffers.[8] He was a consistent presence in the lineup throughout the season, starting in every match except one.[3]
Despite initially extending his contract with Quick Boys,[9] Offerhaus signed his first professional contract with Eerste Divisie club Telstar on 21 May 2024.[10][11] He made his professional debut for the club on 9 August 2024, in a 3–2 away victory against recently relegated Vitesse. Starting the match, he played the full 90 minutes and contributed two assists.[12][13]
Personal life
Offerhaus was born in Heerhugowaard but grew up in Midwoud. Outside of football, he previously worked as a project coordinator at a construction company. He left this job in 2024 to fully focus on his professional football career with Telstar, stating, "Working can always come later; being involved with football every day is the most rewarding thing."[14]
