    My Reviews

    I have worked on many banking cases and claims with Simon over the past 12 years. His knowledge of banking issues is second to none, and his expert reports are always models of clarity.

    Simon and I have worked together for several years, and his knowledge and expertise on banking issues is vast. His knowledge of banking issues has been extremely useful in several cases.

    I used Simon for a claim entered versus a British Bank on a loan contract. The result that he helped us obtained changed our business overnight. We are so thankful.



    Simon helped me in a bridging loan claim, where his expertise of the regulations was encyclopaedic. Simon has a grasp of the laws which is useful alongside his knowledge on banking and financial issues.

    Simon’s knowledge proved extremely useful in a case against a bank which was, for us, extraordinarily complex. Without him, we would have been lost.
