The chief executive of Raleigh International is to step down after 13 years in the role.
Stacey Adams said yesterday that she would leave the sustainable development charity at the end of the year.
She said she would be "developing more of a portfolio approach to my work" and planned to complete her training as a psychotherapist when she steps down from Raleigh International.
She said she was also open to opportunities in fields of leadership development, coaching or interim management.
"My long-term aim is to return to my first love of working deeply with individuals to support them," she said.
She said leadership "was about knowing when to pass on the baton".
Adams said: "The future is bright at Raleigh: we have a strong team and innovation is at the heart of our work.
"We’re also engaging more young people than ever before, and we are reaching a much wider range of backgrounds in the countries we’re working in and globally. We’re a broad, robust organisation with a much clearer understanding, and evidence of the change that can be achieved by working with young people."
Income at the charity, which runs expeditions that enable young people to help communities in Nepal, Costa Rica and Tanzania, has grown steadily in recent years, according to accounts filed with the Charity Commission. Its income was £8.6m in 2017, up from £6m in 2013.
Khalid Koser, chair of Raleigh International, said Adams would be a hard act to follow.
"One of the most important things she achieved was to transform Raleigh from an organisation focused on enabling UK youth to experience other environments through expedition, to a development charity that is focused on empowering young people from various parts of the world to deliver the sustainable development goals," he said.
"Stacey leaves us in a very strong position, and I believe in the direction we’re taking as a result of her work."
The charity said Adams had not yet revealed any future plans. Raleigh is expected to start the process of recruiting a new chief executive soon.
