Mark O’Sullivan is a very kind and professional solicitor. He represented for me on the court and the case finally had a very positive outcome. In the past seven months, he and Matthew Kenny made great efforts for my case. They always replied and explained with patience, dedication, and professionalism. I do not know how to express my appreciation for their help.They had changed my fate and I can continue to pursue my study in Ireland. Thanks for everything they have did. (F.N. December, 2020)
