"Oisín McLoughlin, Matthew Van der Want, Andrew Nagle and the entire Ogier team were excellent. I really valued the contributions from them. I have never met a law firm like Ogier. They moved at speed and brought clarity. Some lawyers can complicate things, the Ogier team made things simple. I have never been as impressed with any advisors like this."

"Oisín McLoughlin and the team were focused and friendly, but firm. They supported me every step of the way."

Client feedback, 2024

"a pleasure to work with, making any project an enjoyable experience… knowledgeable about their subject matter, but are extremely pragmatic in its application which has facilitated complex transactions in a short timeframe in our experience…particularly impressive in their responsiveness and ability to stay calm and organised in complex situations…"

Client feedback, 2023

"Your pragmatism and willingness to get things done – particularly given the tight timelines – was refreshing and very much appreciated"

Client Feedback

"Because we were dealing with multiple jurisdictions, the process [on the acquisition of our company] was complicated and detailed and required considerable coordination ability. […]. No issue, no matter how small, was left unresolved and the quality of what was delivered was clear to all in the ultimately successful process"

Client Feedback

"In my experience most corporate lawyers like to believe they are ‘commercial’ and yet this rarely seems to translate into tangible progress on a sensible timeframe. In contrast, your pragmatism and willingness to get things done – particularly given the tight timelines – was refreshing and very much appreciated"

Client Feedback

"Oisín McLoughlin demonstrated good business acumen and provided commercially focused and practical advice. He came up with solutions even for unforeseen problems and unexpected pushbacks from the sale side. He did very well."

Client feedback, 2024

"… clear, practical and very easy to work with."

Client feedback, 2024

"We really enjoyed working with Sharon Meaney and Oisín McLoughlin. They were very commercial, fast and are great to deal with."
