Our Structure

WANO consists of a Governing Board, a central office in London and regional centres in Atlanta, Moscow, Paris and Tokyo, each with their own regional Governing Boards. Policy is set by the Governing Board and all policies and programmes are implemented by the WANO London office and the regional centres.

WANO organisational chart

Governing Boards

WANO’s Governing Board is accountable to the members for the association’s overall direction and success. To promote direct engagement of members at a high level, the Governing Board includes three members from each regional centre in addition to the Chairman, President and Chief Executive Officer (CEO).

Each regional Governing Board Chairman is automatically a WANO Governing Board member and the regional Governing Boards each nominate two additional candidates from their region, one of whom is expected to be the chief executive that represents the area’s largest or most influential member.

WANO’s Chairman is elected by the Governing Board for a four-year term and can serve for no more than four consecutive years, unless the Board decides otherwise.
