Born in Kilcormac, County Offaly, Screeny first came to hurling prominence at juvenile and underage levels with the Kilcormac–Killoughey club. He first appeared on the inter-county scene during a two-year stint with the Offaly minor team where on his second year captained the side before later lining out with the under-20 team.[1][2] Screeney was still eligible for the under-20 grade when he was drafted onto the Offaly senior hurling team and was a substitute on their 2021 Christy Ring Cup-winning team.[3]
