Spark Arts for Children Director ADEL AL-SALLOUM is set to leave on October 29.
Al-Salloum, who has led the charity for nine years, will take up a new position with UNBOXED 2022.
Al-Salloum developed the organisation into a "strategically-positioned children's arts organisation" that boasts a year-round multi-art form programme.
"Everyone has allowed me to take risks, be bold and lead the company in new directions. I am very proud of the things we have achieved together," Al-Salloum said.
Trustee KAREN BIRCH will step down from the board to become interim Executive Director.
