The crime reduction charity Catch22 has promoted Chris Wright to chief executive.
He has been chief operating officer at Catch22 since it was formed through the merger of Rainer and Crime Concern in 2008.
Wright, who joined Rainer in 2006 as director of services, will take over from Joyce Moseley, who retires on 1 August.
Moseley, who was chief executive of Rainer for nine years before the merger, previously said that she would leave the organisation at the end of the year.
A spokesman for the charity said she would retire earlier than expected because the charity had appointed an internal candidate.
"At the start of year, when the recruitment process began, it was anticipated someone might not come in until three or six months after their appointment," he said.
"Obviously we have found an outstanding internal candidate who can take up the position more quickly."
In a statement, Jim McKenna, chair of Catch22, said: "Chris’s commitment to supporting the needs of young people has always been apparent in his work at Catch22.
"Moreover, he has been at the forefront of developing new business initiatives and building new and exciting relationships between Catch22 and other organisations in the public and private sectors."
