The firm is particularly strong in the areas of M&A and corporate governance. Chairman Ciarán Bolger concentrates on public and private M&A, as well as joint ventures and private equity. He is also a “trusted adviser” on corporate governance matters. The “intellectually gifted” Colm Duggan provides a service that is “second to none” previously heading the firm’s corporate department. There is “no comparison” to Michael Meghen, who specialises in joint ventures and cross-border and foreign investment transactions. Geoff Moore is an “expert” in corporate finance and advises on public offerings, private placements, mergers and acquisitions. Managing partner Brian O’Gorman is “a doyen of corporate law” with extensive experience in public offerings and private placements. He is also recognised for his corporate governance expertise. Declan Hayes is an “expert” in insurance M&A, MBOs, venture capital finance and joint ventures. He is also highly knowledgeable in the life sciences industry. Head of the company compliance and governance practice Thomas Courtney “deserves a place among the world’s leading lawyers”. His achievements include leading the Arthur Cox team which advised the Department of Finance on the design of the Credit Institutions (Stabilisation) Act 2010. The “terrific” Eugene McCague specialises in advising both public and private companies on all aspects of company law as well as advising on corporate governance matters. Pádraig Ó Ríordáin, the former managing partner of the firm, is “unrivalled” in his successes. Specialising in public and regulated sectors, he is well known for leading the Arthur Cox team which provided legal advice to the Irish state and state entities in implementing policy related to the Irish banking crisis.

The firm boasts a “market-leading” IT practice covering a wide spectrum of advisory matters and disputes. Partner and head of technology Rob Corbet focuses on technological innovation and the protection and commercialisation of intellectual property. Patrick McGovern is a “fine lawyer” and head of both the telecommunications and broadcasting group and the utilities, energy and resources group. Clients admire his “outstanding business mind” and his “superior knowledge” of the IT sector. Leading the technology-focused operation in Silicon Valley, John Menton has a “deep understanding” of the industry. Formerly the head of the technology and intellectual property practice at the firm, Menton has an “impressive reputation” and specialises in representing global technology companies that have operations in Ireland. Pearse Ryan is “extremely smart” according to clients and peers.  He is the “go-to guy” for complex computer fraud issues and also specialises in e-commerce, intellectual property and sourcing, outsourcing and project work.

Arthur Cox has a “highly impressive” life sciences practice, with lawyers specialising in the full spectrum of the field. Head of the firm’s life sciences group, Colin Kavanagh is a “leading professional” with “superior knowledge” of the life sciences and creative industries. Based in Dublin, Kavanagh works with both domestic and international companies who operate in Ireland. Isabel Foley, who heads up the product liability and product safety group in Dublin, is “superb” at what she does and possesses a “wealth of knowledge” in the life sciences arena.

Declan Hayes has “extensive experience” in counselling international and domestic clients with regulatory and intellectual property issues in the medical and pharmaceutical industries.

It remains a key aim of Arthur Cox to maintain its involvement within the community. The firm’s corporate social responsibility (CSR) programme focuses on pro bono work, volunteering/charitable activities, employees and the environment. From time to time the firm’s CSR committee selects partner organisations to whom the firm will provide pro bono services and currently, Arthur Cox supports the Lex Mundi Pro Bono Foundation, which provides legal assistance to entrepreneurs who are finding solutions to some of the world’s most pressing global issues.



Arthur Cox runs an equilibrium programme that incorporates a series of seminars and events on health and life/work balance for employees. Subjects including health checks, personal finance advice, creative thinking and communicating with your child have all been on the agenda.

In addition, the firm promotes a family-friendly flexible arrangement available to staff and a general culture of equal opportunities, diversity and inclusivity.



The future for Arthur Cox will likely see more high-profile and complex instructions as the firm looks to maintain its position in Ireland and expand its international reach.
