  • Hi Damien. I wish to thank you and Karen for all your help with the criminal matter, your help was appreciated through the whole process that was seamless from start to finish. The result was excellent and I was relieved with the outcome. Thanks again for all your help.

  • Karen Espiner and Damien Mahon handled a legal matter for me recently, and I couldn’t be happier with their professionalism and the outcome. I would highly recommend them to anybody seeking the highest quality legal assistance & representation.

  • I just want to say thank you to Damien Mahon for his professionalism while acting in my matter. He took all conceivable steps to present my case to satisfy the Magistrate and get the best possible result. I couldn’t have asked for a better outcome, given the nature of my traffic offence. I had to attend a Court appearance on my birthday and the result was the best gift I have ever received. Thank you again Damien, you’re an outstanding lawyer. Greatly appreciated.

  • I would like to thank Damien for making this difficult and stressful times so much easier by his wealth of knowledge and helping me through this difficult time. When I first met Damien he made me feel very comfortable and confident he can deliver a good result, which he did. I am very glad I met the right lawyer to handle my case. Thank you for all your efforts and support. Kind Regards,
