Kirsty O'Sullivan (Halliday)
Kirsty is a theatre artist, director, writer, youth theatre tutor, acting teacher, and public speaking coach with over 20 years of experience - and for the past 15, she has also been taking the skills developed on stage and putting them in boardrooms, conference centres, and training rooms.

Kirsty trained as an actor then musical theatre performer, and went on to study Drama and Performance. She took over and ran her own acting school in her twenties and says the Edinburgh Acting School shaped everything about how she understands teaching, communication, and what it takes to help another person find their voice.

Since then, she has taught actorss the UK, Italy and in Cayman. She worked with some of Scotland's most respected theatre organisations including Scottish Youth Theatre, Brunton Theatre, Stagecoach, Razzamatazz, East Lothian Youth Theatre Network. Kirsty later completed a Masters Degree in Shakespeare and Education with the Royal Shakespeare Company through the University of Birmingham. This deepened her understanding of how language, voice, and text work create a deep impact in communication.

​

Kirsty's approach has always been inclusive, and she holds a diploma in Autism Awareness, as well as having volunteered as a support worker for Lung Ha's, Scotland's leading inclusive theatre company. Kirsty holds a certification in Assertiveness Training because she strongly believes that confidence in communication isn't just about performance, but knowing your voice and using it effectively. On top of this Kirsty completed the Toastmasters Public Speaking Skills Professional Certificate in order to bring the worlds most respected public speaking framework into her corporate training practice.

As a writer, recent original works have appeared in the Edinburgh Festival Fringe, and the world famous A Play, A Pie, and A Pint. Kirsty also won the Ena Watler Playwriting Award through the Cayman National Cultural Foundation. Kirsty's work can still be seen in high schools across the USA for her adaptations, as well as BTA's very own murder mystery event add-on.

As an actress, Kirsty was signed and doing acting jobs with Stiven Christie Management for many years before her relocation, and has a background in theatre (with a pinch of screenwork too). But she feels this bio has gotten long enough to skip listing these!
