David Marston


Founder of David Marston & Co

David qualified as a Chartered Accountant in 1976. His early career took shape in small to medium Chartered Accountancy firms but, rather than accept the partnership opportunities offered to him, he decided in 1986 to set up his own firm, David Marston & Co. David’s practice has been built up on a culture of focusing on clients’ needs and delivery of a very personal service, a culture shared by MG Group. The firms merged in September 2017 to allow for a smooth transition to David’s eventual retirement after a long and successful career.
