What Service Users Say

This office instructed Michael O Connor to act as a mediator in respect of a very significant contractual dispute between two commercial entities. Initially, the only perceived remedy was to go to the High Court. However the issue in dispute was referred to Michael, as mediator. Michael organised the mediation in a timely, transparent & professional manner. Although the parties were initially diametrically opposed, common ground was found, and through his capable hands, a sensible negotiated settlement was ultimately reached and implemented by the parties. This saved at least €100,000 in fees and was completed in a matter of weeks from start to finish. The parties were delighted with the outcome. Their professional relationship was salvaged and they continued to work together. This was an excellent outcome thanks to Michael’s capable hands.

I have appointed Michael as mediator in a number of difficult disputes over the last few years and I have found his intervention invaluable. In all cases it has either led directly to a settlement in the matter or paved the way for a settlement ultimately. His record of success as far as I am concerned is 100% and there are few other examples I can think of which even approaches this. He is a skilful and very personable professional who displays the best attributes of our profession and he has the best interests of the clients at heart in seeking to find a way to an honourable and fair solution that all parties can live with which allows them to move on in a respectful manner. He is also prepared to stick with the process for as long as it takes and a result and this is a great asset to have. I would have no hesitation in recommending Michael as mediator to anyone. First class.
Yours sincerely

Happy to support my hard working and wonderful colleague and friend, Denise Waldron BL, for the Bar Council elections 2026. Pictured here also at a Western Circuit night out in Clifden are Grainne Quinn BL and the lovely Catherine Walsh BL (R.I.P). These three used to kill me in Court and then we would forget it again and enjoy a night out – one of the lovely traits of the Bar and sadly a feature under steady erosion as time goes by.

A proud day yesterday for Presentation College Headford when one of its past pupils Andrew Reddington was elected Cathaoirleach of Galway County Council. Meanwhile outgoing Leas Cathaoirleach (and former Cathaoirleach) Mary Hoade and Cllr James Charity both also past pupils paid tribute to Andrew and PCH on a special day for him, his wife and family especially his parents who were in the Chamber. Sometimes we only hear the negatives but listening to them yesterday mentioning their school days in PCH made me reflect on my days in PCH and on the gift the Presentation Order and the wonderful John Bonner and all the teachers gave us in the fine free for everyone school that was and is PCH. Also among other former PCH students present was Maria Walsh MEP as well as many other leaders in business, industry and the professions. It’s worth recalling too that the nuns gave access to the land for Moyne Villa Soccer and Corrib Rugby as well as a girls GAA Pitch that was badly needed.
