About Me

I am the head of the corporate/M&A team in Ireland where I specialise in advising companies and investors on mergers and acquisitions, equity fundraisings, joint ventures, shareholder arrangements and corporate reorganisations. I also support my clients with corporate governance, compliance and commercial matters.

My practice covers a broad range of industries, including the technology, aviation, life sciences, manufacturing, retail and financial services sectors and I represent companies through the full corporate life cycle, advising them on establishment, fundraising for growth and exit.

Ireland, as a gateway to Europe, continues to be an attractive location for foreign direct investment. I enjoy playing my part in helping to bring this investment to Ireland by advising clients on the establishment of operations here, either by way of acquisition or other form of strategic investment.

My primary focus is to achieve the desired result for my client. As a corporate lawyer with almost 20 years' experience, I understand that leadership, pragmatism, commercial acumen and transaction management are paramount to execute the best strategy and complete a deal on time and within budget.
My clients can rely on me to adopt a calm, common sense and good-natured approach when working with them to achieve their strategic goals and personal ambitions.

At Bird & Bird, I am fortunate to work with a global team of best-in-class lawyers who bring significant value to my clients, in particular those businesses embracing innovation and the challenge of digital transformation. Our one firm international offering allows us to develop long lasting client relationships and to provide outstanding and consistent client service on cross-border matters.
