He will also be responsible for providing strategic expertise to the division by delivering on recent client wins, as well as working with the leadership team to develop the banking and capital markets (BCM) tax advisory proposition.
Catherin Hall, head of tax at Mazars, said: “I am delighted that Mark has joined the partnership, and we welcome him to the team here in London.
“We have ambitious plans for growth across the financial services strategic market, specifically within the financial services tax team.”
