I would not hesitate to appoint him again.”


"Mark provided precise technical analysis on a number of very complex quantum matters. I have found his reports and opinions clear, thorough and concise yet containing the requisite detail. I have enjoyed working alongside Mark and look forward to working with him again. I would not hesitate in recommending him in the future."


"I worked with Mark on a highly complex, multi-billion power station project. He always ensured that project reports were delivered on time and of the high standard that I expect. What I particularly appreciated was Mark's hands-on service mentality, and of course his excellent technical skills - not only in his field of play, but also regarding other relevant disciplines like project management or legal matters. Besides, working with Mark was always pleasant and enjoyable and Mark's attention to detail meant that we were able to produce accurate and convincing analysis and assessments of complex issues. I look forward to working with Mark again and would recommend him any without hesitation."
