Chambers report that he is a '"brilliant and driven" practitioner, lauded for his arbitration work and his handling of high-profile cases in the energy sector.' Additionally, he ‘has impressed clients as a strategic thinker and devoted counsellor. "Apart from  giving spot-on analysis, he made the effort to really get to know our company," one interviewee said’.
