  • Hobbies: Given a Longford man’s GAA season is often ended too quickly, I would often swap one blue jersey for another to cheer on Leinster rugby. I can also be occasionally found at the side of a racetrack!
  • Best piece of advice you've ever received: “There is nobody better or worse than you in this world, so treat everyone as your equal and make sure everyone treats you as their equal too” – from a brilliant Irish mother who always kept me on the straight and narrow!
  • Why you love your job: I enjoy an initial meeting with a new client to find out about their business and see the angles where we can help. Entrepreneurs and business owners have such great stories to tell and are rightly so proud of their achievements that it is great to just sit and listen to these people, and if we can offer some valuable advice, then all the better!
  • Motto for life: “Always get back on the horse”.

  • Why you love your job: It comes down to people. I get to work with great clients and a supportive team. I enjoy making things clearer for others and helping them make better decisions. That is where I get the most satisfaction.
