Ambassador Theatre Group has appointed Elizabeth Adlington as area theatre manager to run both Aylesbury Waterside Theatre and the New Theatre Oxford.
This follows a similar pattern to other ATG venues, such as those in Stoke-on-Trent, Glasgow and London, in which one manager runs multiple venues.
Previously, ATG has also operated venues in Brighton and Bromley, as well as Wimbledon and Richmond in London, in this way.
Adlington was made chief executive of the New Theatre Oxford last September, and will continue her responsibilities within this role as part of her new position.
At the same time as being chief executive of the Oxford venue, she held a strategic role at the Aylesbury Waterside Theatre alongside general manager Jamie Baskeyfield.
Adlington had previously run the Waterside from 2009 to 2012. For almost a year during this period she also ran Milton Keynes Theatre.
ATG said Baskeyfield will leave the theatre “to pursue other opportunities”.
A spokesman from the company said Adlington had been given her new role due to the “close working relationship” and “complementary programming requirement” of the two theatres.
He added: “This is a structure that ATG has used previously in the regions where substantial synergies make it effective. Elizabeth held a similar role previously, which she fulfilled with great success.
“She will be working to ensure that the diversity and quality of programme that Aylesbury audiences have enjoyed since the opening of the venue in October 2010 will continue, and that the New Theatre’s history of bringing the best live entertainment to Oxford will continue to grow.”
