Newcastle Theatre Royal chief executive Philip Bernays is to step down after 15 years in the post.
He will leave at the end of this year, having been in the role since 2005.
The theatre said it had seen “audiences and turnover rise” since he joined the theatre, with the venue being named the UK’s most welcoming theatre in 2015.
He also oversaw a renovation of the building, which coincided with its 175th birthday in 2012.
Bernays said: “I have loved every minute of what will be 15 years at the Theatre Royal. It really is one of the finest theatres in the country and it has been an honour and a privilege to lead it through such exciting times.
“I have worked with a fabulous team in this fabulous building, presenting some fabulous shows – it’s been the best job I’ve ever had and I will of course miss it, but retirement and a slightly quieter life beckon.”
Nick Swales, chair of the Newcastle Theatre Royal Trust, said Bernays had steered the venue through “some difficult times”, including the loss of its funding.
But he said Bernays would leave the theatre “thriving and its future at the heart of the North East assured”.
He will stand down in December 2020, with a recruitment process for the new chief executive commencing in the next few weeks.
