He was managing director of Windsor Safari Park for five years followed by six years with Center Parcs, a company that set new high-standards for domestic tourism in the UK during the 1990s. Having accepted a move to join the Walt Disney Company in Paris in 1998, he was persuaded instead to take up the role of managing director of Leisure Parcs Ltd, owners of Blackpool Tower, and to lead the campaign for resort casino development to be used as a catalyst for the economic regeneration of Blackpool.

Marc was appointed Chief Executive of the Responsible Gambling Trust, now called GambleAware following the merger between the GREaT Foundation and the Responsible Gambling Fund (RGF) in April 2012.
