"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"
