  • Having worked with Joanna McKenzie over many months on a complex and challenging piece of litigation, I can safely say that no one could have been a more devoted lawyer to her client. She works tirelessly at all hours of the day and night with razor sharp attention to detail. Not only is she able to empathise with her clients but she has a thorough knowledge of the law. She manages to orchestrate members of a multidisciplinary team comprising client, counsel and expert witnesses with the apparent ease to get everyone working together in an efficient and coordinated way for the client’s benefit.

  • I have worked as counsel with Keystone Law, and in particular Joanna McKenzie, in litigation in the High Court and Court of Appeal, for a number of years and found the firm and Mrs McKenzie to be exceptional team members who make a very substantial contribution to the efficient and effective conduct of litigation. I am especially impressed with the firm’s client care in terms of attention paid to the client and the firm’s flexibility in serving the needs of their client.
