Mason Hayes & Curran LLP's large corporate and M&A practice has seen an uptick in renewable energy, life sciences and corporate technology deals. The team is highly regarded for its strength in handling cross-border mandates, often involving US investors, and has a growing presence in the private equity space. Mid-market deals and transactions involving growth companies and start-ups are also included in the group's workload. David O’Donnell is a seasoned practitioner, and Justin McKenna is a key name in the practice for public M&A transactions. Other key practitioners include head of the life sciences team Martin Kelleher, Liam Brazil, corporate governance and compliance expert Claire Lord, and the 'pragmatic and experienced' Conall Geraghty.

Testimonials
Collated independently by Legal 500 research team.
‘I would commend Mason, Hayes and Curran for their work, in particular Dermot McGirr, for his professionalism, courtesy and insight in regard to the legal services we required. Their attention to detail was of particular reassurance to us and reflected the high standards we have come to expect from Mason, Hayes and Curran.’
‘The MHC team (particularly Conall Geraghty) are extremely hard-working, responsive and creative in finding solutions to difficult deals. What sets them apart from other law firms we worked with is that they're also very pragmatic. They'll tell you what's worth fighting over and they understand business perspective. ’
‘Conall Geraghty - very friendly, hard-working, full of empathy (which instead of aggravating the other side, makes the whole conversation more productive), pragmatic and experienced. ’
‘Liam Brazil was excellent. Liam's knowledge of corporate governance type matters are second to none. Liam stays focused on the outcome and has the tenacity to get the deal done.'
‘I have worked with Eimear Lyons on our projects. She really knows how to manage a project in such a way that requires minimum input from the client, which is highly appreciated. Furthermore, she understands the commercial aspects and business needs behind the purely legal aspects of a M&A deal and therefore knows exactly how to negotiate the terms of the deal, in a swiftly manner.’
‘Talented people, clear leadership, strong commercial mindset, efficient delivery.’
‘David O'Donnell: exceptionally commercial and practical.'
