Polly fell in love with the whole enterprise of theatre when her parents started presenting opera in their garden when she was five years old. In 2013 she became the Genesis Assistant Director at WNO and worked there for two years, mentored by David Pountney. She directed Peter Maxwell Davies' Kommilitonen! for WNYO in 2016 and Frank Martin's Le Vin Herbé in 2017. Both productions won Best Opera at the Welsh Theatre Awards. In 2016 she also directed the UK premiere of Simplicius Simplicissimus by Karl Amadeus Hartmann, as Independent Opera Director Fellow.
She was listed in the 2017 Ones to Watch in the Guardian. She now works as a freelance director and in 2017 founded her own company, Loud Crowd, whose first production, The Emperor of Atlantis, was presented at Bold Tendencies in September 2018.
She has two young children. Polly is Artistic Director for Longborough Festival Opera.
