Martyn Craddock has been appointed chief executive of Southwark's United St Saviourís Charity.
Martyn Craddock has been chief executive of St Lukeís Trust in Islington since 2007 and will up his new role in early next year.
"I am very excited by the challenge of leading United St Saviourís Charity," said Martyn Craddock when his appointment was announced on Tuesday morning.
"I share the passion of St Saviourís trustees to improve the lives of Southwark residents and their ambition to build a brand new almshouse for Southwark pensioners on limited incomes.
"We will also devise ground breaking ways of investing in North Southwark and Bermondsey to build strong communities and tackle isolation and poverty."
The appointment follows the decision of Jim Wintour to retire after more than four years as Director.
During this period St Saviour's acquired Hoptonís almshouses and opened applications to women as well as men. The charity's annual grant giving to community groups more than doubled.
"Jim Wintour has been brilliant as our Director for four years," said St Saviour's chair Richard Heaton.
"The Charity has moved on enormously and is now in a strong position to help more people than ever before.
"Many colleagues, residents and community groups across the borough will miss Jim, and will join me in wishing him a very happy retirement"
United St Saviourís Charity, also known as the Corporation of Wardens of the Parish of St Saviourís, was founded during the reign of Henry VI as the Guild of the Fraternity of the Blessed Virgin Mary. The charter was granted by Henry VIII.
