After nearly 20 years of service to the SECC, Closier will step down at the end of the month.
SECC chairman Sir Ian Grant said: "Mike has made an outstanding contribution to the success of this business during his time as chief executive. He was the inspiration and driving force behind the development and construction of the Scottish Conference Centre, the ‘Armadillo’, which has become a global icon for Glasgow since it opened in 1997."
Closier also led the planned redevelopment of the SECC site, the QD2 Project, to enable the construction of the Scottish National Arena.
The new board is in place from immediate effect, with the new Scottish National Arena set for a 2013 launch ahead of the Glasgow Commonwealth Games in 2014.
