Oonagh Aitken, chief executive of Volunteering Matters, has announced her retirement after seven years at the charity.
Aitken, who has spent the past five years as chief executive of the charity, said in a statement today that she would step down at the end of June.
She has led Volunteering Matters through a name change – it was formerly Community Service Volunteers – and a refocus on its volunteering and social action work, the charity said.
The charity has 30,000 volunteers working in more than 100 different programmes and supports about 115,000 beneficiaries, according to the charity.
Aitken previously worked for Glasgow City Council and Fife Council, and started her career in teaching.
The charity said the search for Aitken’s successor was under way.
Aitken said: "It has been a great pleasure and a privilege to serve as chief executive for such an extraordinary organisation, which I sincerely hope will go from strength to strength. I would wholeheartedly encourage people to apply for this leadership role."
Anne Heal, chair of Volunteering Matters, thanked Aitken for "seven years of dedication to the charity".
She added: "In that time she has refined our strategic direction, updated our identity to better reflect what we do and ensured we are recognised as one of the UK’s leading volunteering charities.
"Oonagh will be very hard to replace, but we will do our very best to find a brilliant successor to take Volunteering Matters forward."
