His previous experience as a corporate lawyer and his five years as a non-executive director of a publicly listed company (plc) give him a unique insight into the issues facing investors, entrepreneurs and overseas businesses establishing operations in the UK and enables him to devise and implement coherent and compatible structures and solutions.

He is recommended by Legal 500, where he is described as being 'proactive and imaginative', and Chambers Guide to the UK Legal Profession, where he is noted as being 'charismatic' and 'clever' and 'a sought-after name'.
