‘This practice has better people than any other practice I have used before. I know there is a cliche about merely stating that the people are what makes a company better. However a balance of emotional intelligence, profound natural ability, resilience and most importantly being easy to work with is what the various people have in common. I noticed this from the junior members of staff and the senior ones. They also have a variety of people to call upon and they don't take risks by guessing important issues, they have the self discipline and intelligence to pull in the right people in each scenario.’
‘Niamh Caffrey advised me on issues around tax, governance and other various items. She was stunningly patient with me. I had many people telling me how to save money on tax. She worked through each scenario with me and allowed me to be informed enough to make my own choices. I felt comfortable, never pressured and very importantly, never stupid. Niamh was challenged by people from the other side, but my feeling was that she had my absolute true best interest at heart. She showed knowledge, patience and reliance as well as a depth of knowledge to back it up. I also loved the way she was happy to discuss any option with anyone. She was unflappable in circumstances where the other side was needlessly irate. I couldn't recommend her highly enough and she undoubtably saved me from future issues.’
‘Niamh Caffrey was outstanding from start to finish and always available. Aisling Buckley delivered consistently and in clear, concise terms.’
‘Kevin Mangan is a stand out addition to the team. His advice is always clear, concise and commercially grounded. He is calm under pressure and extremely knowledgeable. ’
