Ms Kavanaugh is leaving the REP to spend more time with her family
Birmingham Repertory Theatre Company is looking for a new Artistic Director after Rachel Kavanaugh announced she is stepping down from the role.
Ms Kavanaugh has been the creative leader of the theatre since 2006, directing a variety of shows in her time including The Wizard of Oz.
Her decision comes as the REP embarks on a new phase in its rich history.
The theatre is moving from Centenary Square, its home since 1971, to a new Cultural Centre in 2013.
The multi-million pound development will see the REP become integrated with the new Library of Birmingham in the West Midlands Cultural Centre adjacent to the theatre's current home.
"As the REP is soon to enter an exciting phase of development, it feels like the right moment to hand over to a new Artistic Director who can build on our current successes," Ms Kavanaugh said.
"I have had the opportunity to work with some amazing artists and hugely dedicated staff. It's a thrillingly diverse and creative company in which to work."
Ms Kavanaugh is stepping down in the spring of 2011 in order to spend more time with her family and to pursue a freelance career.
"Rachel has been an outstanding Artistic Director and has taken the theatre to new heights during her tenure," Ian Squires, the chairman of the REP said.
"We quite understand her decision and we wish her well and look forward to welcoming her back in a freelance capacity in the future."
The REP was founded in 1913 and has played host to some world-famous names over the decades.
They will continue to put on productions at a number of different venues across the West Midlands for the next two years while its new home is being built.
