With excellent facilities and a strong community spirit, the club continues to play a vital role in the local area, and we’re proud to support them as they look ahead to future success.

Pictured we have Mark Pearse - branch manager, Nara, Conor and Seamus meeting with Club Secretary Gary Culbert ,Club Treasurer Phil Madden and Mark Gennery to present a number of sponsored gilets for players ahead of the 2026 season.
