Born at 318ppm CO2 Now it’s 422.

I am a senior counsel, solicitor, arbitrator, accredited mediator and conciliator. Since 1983 I have specialised in dispute resolution and construction and infrastructure law.

I am a BCL and LLM graduate of University College Dublin and received the degree of Barrister-at-Law from Kings Inns. I’m a Fellow of the Chartered Institute of Arbitrators, a CEDR accredited mediator, and a member of the Law Society panel of arbitrators and Engineers Ireland panel of conciliators. I currently serve on the International Court of Arbitration of the International Chamber of Commerce, and on dispute resolution committees of the Law Society of Ireland and Engineers Ireland.

I was called to the Irish bar in 1983 and practised as a barrister for three years. In 1987 I was admitted in California, where I practised construction and government contract law until 1996. I acted in disputes arising from projects such as the Golden Gate Bridge deck replacement, urban railways, highways, water and wastewater treatment plants, airports, prisons, hospitals.

From 1996 to 2004 I practised construction and infrastructure law in a global law firm’s UK and Irish offices, where I was elected partner. In 2004 I joined one of Ireland’s biggest law firms as a partner, and continued to specialise in construction and infrastructure law, leading the construction practice group in its litigation department. I advised on most of Ireland’s major public infrastructure projects in the last 20 years, including these. I drafted the standard construction contracts used for almost all Irish public projects since 2007, and also the arbitration rules for public contract disputes. My practice also included commercial litigation, arbitration and mediation.  And I was responsible for instituting and leading that firm’s pro bono practice, including initiatives to advise and represent people seeking asylum and international protection and people experiencing or at risk of homelessness. I acted for the UN High Commissioner for Refugees as amicus curiae (friend of the court) in three cases before the Irish courts.

Since 2020, I’ve been in sole practice, focusing on dispute resolution, construction and infrastructure, and human rights and business.

In 2020, I made history by being one of the first solicitors ever designated senior counsel by the Government of Ireland. Seventeen were selected for excellence as advocates or legal specialists.
