Allan’s appointment to the role, which is equivalent to the organisation’s chair, will be formally agreed at the SCVO’s annual general meeting in Edinburgh this afternoon.
She takes over the position for an initial three-year term from Alison Elliot, who stands down after completing six years in the role, the maximum allowed by the SCVO’s constitution.
Allan, who was also a director of the Edinburgh Association for Mental Health and is vice-chair of the Lothian Health Board, was awarded an MBE in 2010 for services to the voluntary sector.
"I particularly hope to have opportunities to ensure that the sector's varied work, its interests and the knowledge and experience that lie within it are promoted and increasingly recognised and valued," said Allan.
"I am sure there will be both opportunities and challenges for the board, and for SCVO over the next three years. I relish having this role in an organisation I have known for many years and hold in great respect."
