A selection of testimonials from yet more satisfied clients


From the Managing Director of an Irish building and civil engineering firm in the CIF’s Top 10

Over the past number of years we have engaged John Farage O’Brien as external consultants, providing specialist expertise and advice on a broad range of contractual matters.

John O’Brien’s depth of knowledge and mastery of legal and contractual issues, his practical understanding of the construction process and his ability to apply strategic thinking to complex matters of dispute have been an invaluable asset to our company.

What further differentiates John is the enthusiasm and level of commitment he brings to the process, and his ability to work collaboratively with our in-house staff and our external consultants to develop commercial resolution strategies and achieve successful outcomes on our behalf.

We will continue to retain John’s services in the years ahead and wholeheartedly recommend him to any business in need of wise counsel and good guidance in this area

Glenn Nunan | Principal

GNCE Consulting Engineers

We provided expert technical witness services over many years, working as part of a multi-disciplinary team lead by John Farage O’Brien. A number of complex conciliations and arbitrations stand out. It is without doubt that John’s ability to understand and disseminate interrelated construction activities in a coordinated and focused manner was key in identifying the genesis of the issues, leading to a clear understanding of the events. John’s capacity to view the larger picture while never losing sign of the finer details has proven to be one of his trademarks which, combined with his charisma and determination, makes for a winning team.

I have known John Farage O’Brien for a number of years and have had the pleasure of working with him and his team on a number of varied and interesting cases during that time.  John’s very extensive experience in the world of construction projects allows him to approach clients’ issues in a pragmatic, commercial and highly effective manner.  It is always a pleasure to deal with the firm.

John O’Brien was the case manager in an arbitration I was involved in recently as an expert witness. I was immediately struck by John’s exceptional grasp of the key issues and his ability to analyse, process and link data and information from the various and diverse sources to form a comprehensive overview. John demonstrated a huge and in-depth range of technical knowledge of all aspects of construction, construction and engineering technology, contracts and construction law. I have absolutely no hesitation in recommending John’s firm.

In the words of Lyndon B Johnson, I would rather have John inside my tent pissing out, rather than outside my tent pissing in.






David Richards | Principal


I have worked with John O’Brien for a number of years, having originally been on the opposite side of the table from him on two small roads cases. On three major cases where we have both been engaged together, our mutual clients have enjoyed success on two and await the outcome of the third. John brings vigour, intellect and clear thinking to his case management.

John’s diligent research into the core issues of the dispute, combined with his strategic thinking, provided our organisation with expert advice that was invaluable – literally. His professional modus operandi and presentation skills are second to none.
