The chief executive of the grant-maker the Jack Petchey Foundation is to step down after 14 years in the role.
Trudy Kilcullen will be succeeded by Gemma Juma, who joined the charity as operations director in 2017 before becoming deputy chief executive last year.
Juma previously worked for voluntary sector organisations including the volunteering charity Link Age Southwark, the mental health charity Mind and Comic Relief.
Kilcullen, who will step down on Tuesday, will remain with the foundation, as a special project adviser, on a part-time basis.
She said: “It has been a great joy working alongside the legendary Sir Jack Petchey to implement his vision for young people.
“I have met many committed teachers and leaders – who go above and beyond for young people – both within JPF and in the many organisations with which we work.
“I have also been privileged to engage with so many enthusiastic and ambitious youngsters who are making such a positive difference to our world.
“The work of the foundation is so important, especially in today’s world, and I wish Gemma all the very best as she takes on this exciting mission.”
The charity, which was founded by the businessman Sir Jack Petchey in 1999, supports young people in London and Essex. It also runs the Jack Petchey Achievement Award scheme, which operates in more than 2,000 schools and youth organisations.
Juma said: “Young people are at the heart of all that we do as a foundation.
“I will continue to deliver Sir Jack’s vision and ensure that our programmes support young people to develop a broad range of skills as well as confidence and self-belief.
“My thanks go to the inspirational leaders, teachers, schools and organisations that support young people and give them opportunities to believe in themselves and be the best that they can be.”
