Mark Wrey began his career at Christie’s King Street in 1974 where he worked for 18 years in the Press, PR and Marketing departments, becoming Marketing Director in 1986.

Mark then took responsibility in 1992 for Christie’s interests in the South of England. This involved looking after clients’ needs, providing valuations and selections for sale. The culmination of this period were the sales which he orchestrated from Cowdray Park, involving all specialist art departments as well as advice from the Valuations and Heritage & Taxation departments. This extensive project culminated in some exceptional sales. Mark has been a Senior Director in the UK Chairman’s Office and took on the role of Head of Estates , Appraisals and Valuations EMERI department in 2012.
