He sat as a Recorder from 2002 to 2021. He is an accredited mediator. He is also a Fellow of the Chartered Institute of Arbitrators (1992) and holds a Diploma in International Commercial Arbitration.

Stephen Baister said: “A former solicitor in a respected London firm and, until recently, Chief Chancery Master of the High Court, Matthew Marsh (alongside whom I was privileged to work) brings a unique blend of skills to the Three Stone mediation and arbitration team. The breadth of his practice and judicial experience is complemented by a calm and reassuring personality. Litigants and their advisers will find him effective in a wide range of commercial and other disputes in both capacities in which his services are available.”
