Danny Curtin has been appointed chair of the Association of Chairs, a membership organisation set up six years ago to support charity chairs and vice-chairs in their leadership and governance roles.
Curtin succeeds Ruth Lesirge, who co-founded the organisation with Ros Oakley, the current chief executive.
He is an experienced board member, who first became a trustee in his twenties and has been a trustee of the association for four years.
Curtin, who is from a faith-based background, founded the youth action charity Million Minutes and remains its voluntary chief executive.
"The association has been massively important to me," said Curtin, who will take up the role in September.
"Five years ago, still in my mid-thirties, I was a new chair and in joining the association I found the support and expertise I needed.
"I look forward to playing my part, as chair, in helping to contribute to the next phase of our growth."
He praised Lesirge, who has been made an honorary president, for her "vision, tenacity and hard work".
Lesirge will continue to serve as an adviser and volunteer. She will help to deliver the association’s training and guidance and develop new resources and workshops.
Lesirge said the association had grown to become "something far more than one woman’s obsession".
She added: "Our membership of more than 600 and our wider engagement have proved that the association is valued.
"It has found its place in the sector. So now, after four years as chair, it felt like the right time to pass on the baton to allow me to focus on helping to increase further our networks, our insights and our resources for chairs."
