Chambers succeeds Andrew Mosley, general manager of The Grand Brighton, who remains on the executive board as immediate past chairman, while Jonathan Morris, commercial director at No.11 Cavendish Square, assumes the role of vice chairman.
The executive board will be supported by a new development board made up of elected council members, responsible for developing and leading projects to deliver the association’s objectives, as set by the executive board.
An operations board will complete the governance and resources oversight and support for the executive board, composed of elected and appointed council officers, together with the chief executive.
Chambers said: "Our new executive board is made up of some of the most experienced talents in the hospitality and events industries, ably supported by development and operations boards.
"Appointing this group of professionals creates a newly empowered voice to raise the profile of the work we do with and on behalf of members and the industry. We’ve got lots to look forward to this year and are pushing ahead with more events, more marketing and more sector insight to grow the value of membership."
The announcement was made at the end of the association's recent AGM, at which treasurer Michael Stott also revealed a year-end net surplus for the financial year ending August 2015. Jane Longhurst, chief executive, attributed the growth to events and exhibitions, demonstrating a "pleasing increase in member engagement".
Earlier this year the MIA launched a subsidiary company to deliver membership services to third parties and offer an additional income stream. Membership Support Services (MSS) signed its first contract in February, assuming responsibility for managing the day-to-day operation of events and hospitality association the HBAA. The three-year contract includes membership services, finance and bookkeeping, plus provision of marketing support.
