Lucy Deller has taken over his role, after working at the venue for seven years as an event manager.
Meanwhile Jenny Henderson has been appointed event manager, bringing experience from her previous roles at London-based caterer, Party Ingredients and wine company Villa Maria in New Zealand.
Claudia Baldassarre has also joined the team as event executive from Anglia Ruskin University London, where she was responsible for organising charity fundraising events.
Paul Southern, managing director at Central Hall, said: "It is always sad to say goodbye to staff who have made a significant contribution to the success of the venue and we wish Stuart the very best of luck for his retirement. However, Lucy has an excellent track record at Central Hall, so Stuart is handing over to a very capable successor. We welcome Jenny and Claudia to our dynamic events team and are looking forward to working with them."
