Trinity Credit Union is a community credit union and was originally set up in 1982 by a small group of people who saw the need for a credit union to serve the local area of Donaghmede. Those dedicated few started in an upstairs room in Donaghmede House, opening for a few hours every Friday night. Never in the wildest dreams of those original volunteers could they have contemplated the wonderful achievement of their efforts and the vital role that they played in the success story of Trinity Credit Union Donaghmede. From those humble beginnings, we now have approx. 12,000+ active members. 2019 sees the further development of our online banking system and the introduction of an online loan application service.
