      There are a multitude of solicitors to choose from in Dublin, Ireland. I’m extremely grateful that my wife selected Tiernan & Co. to handle her case. I believe they successfully achieved the best possible outcome for her case. Upon completion of her settlement, she received her funds in an amazingly short period of time. Throughout the entire process it was a pleasure to work with every associate at Tiernan & Co. They were efficient, caring, experienced, very professional, and extremely trustworthy in every way. They definitely earned our respect and sincere gratitude for her successful legal outcome. Thank you Tiernan & Co.!

      Where do I begin, as there are not enough words to describe how highly I recommend Mark Tiernan June O’Neil. Before going to them with my injury claim I had previously endured a 5 year relationship with another solicitor, which was filled with countless setbacks, very little interaction and in the end little to none progress. They acted in their own best interests that were at a detriment to mine. This left me at an extremely low point, with no faith left in the legal system. Once finding Mark and June everything changed extremely for the better, my prayers were answered, my faith restored! The care and level of service given to me was second to none. Absolutely outstanding. They have a different understanding of these sensitive matters, as they were kind and compassionate and listen to what I had to say and we’re always available to answer my questions no matter how small or insignificant they were. They were both in constant contact and kept me updated, while making the process as stress free as possible. I was delighted with the outcome of my case, but what meant the most to me was the personal service, the respect and belief they had for me and my case and to me this was priceless. What had started as a very traumatic experience for me they turned into a highly successful outcome and myself and my family will always be grateful for everything they have done for us. If you want the best team in your corner I highly recommend Mark Tiernan and June O Neill.

      We found Mark and his team to be extremely efficient and thorough from start to finish. With Mark’s legal expertise we were able to get our problems resolved. Would highly recommend Tiernan solicitors to anyone seeking legal advice. Thank you again.

      I cant recommend Mark highly enough, I had serious problems with my previous solicitors not progressing my case in a timely manner or competently so I dismissed them. Mark personally took over my case and I am delighted with the result he obtained for me. My only regret is that I didn’t retain Marks services from the beginning of my case.

      Brian McCarthy

      Found mark himself to be very efficient professional and do everything in his power to get the other side to be fair.would recommend mark and his team as we had a the other side that were draging there heels and have to say mark and his team did not give them a mins peace in order to win. Which he has done and on approximate time give when told us it would done.

      I found the service offered by Mark Tiernan Solicitors excellent. I wish to particularly thank June O’Neill who handled my personal injury case very professionally. She was very helpful and supportive throughout my case and brought it to a very successful outcome. I would highly recommend this firm.

      I was very happy with the services of Tiernan & Co, and in fact have recommended their services to two friends since my claim settled.


      When I was involved in a road traffic accident, I was unsure what to do. From the first time I contacted Tiernan & Co Solicitors until my case was finalised all members of staff kept me updated. They kept things simple, so it was easy for me to understand all aspects of my claim.


      Mark and his staff main priority are their clients, I couldn’t recommend this firm enough.


      I have been a client of Tiernan & Co for years now, Mark has dealt with my house purchase and sale, the probate of my fathers estate and a personal injury case on my behalf. Mark offers a highly professional service with a personal touch. I would recommend Mark to anyone in need of legal advice.


      Any queries I had in relation to my personal injury claim were answered promptly and in a professional manner and in the end the compensation I received exceeded my expectations.


      I always felt that the staff in Tiernan & Co had time to listen to me and respond to any question I asked. As a client I felt I was a priority.


      As it was my first time claiming, I was unsure what to do. Mark and the staff at Tiernan & Co helped me through every stage of the process and answered any question I had, no matter how silly it sounded! To be kept updated throughout the whole claim made it much easier for me and in the end I couldn’t have been happier with the outcome.
