About us.

The bridge between the stage and the boardroom

Jack Starkey-Gill is the founder of JSG Voice and Voice Director at Bell Shakespeare, Australia’s national theatre company. He holds an MFA in Voice from the National Institute of Dramatic Art (NIDA) and a Bachelor of Dramatic Art from the Victorian College of the Arts (VCA).

Jack has worked at the intersection of professional performance and corporate communication since 2019. Before founding JSG Voice, he worked as a copywriter and content strategist at JWT and Hill+Knowlton Strategies – giving him fluency in both the language of the stage as well as the boardroom.

What JSG Voice does

JSG Voice is a specialist consultancy that prepares senior executives and professional services teams for high-stakes presentations. We work with leaders in law, finance, private equity, infrastructure, marketing, education and technology, typically when board presentations, investor pitches, or client meetings carry significant consequence and the preparation needs to match.

Our approach takes the same conservatoire-level techniques Jack uses to prepare professional actors for Bell Shakespeare’s stage and translates them into practical, physical frameworks that executives can apply immediately. This isn’t motivational speaking or generic public speaking tips. It’s rigorous, evidence-based vocal and physical training built on the pedagogy of master voice practitioners.

Who we work with

JSG Voice provides executive coaching and corporate workshops for C-suite executives preparing for board presentations, senior partners at law and professional services firms, founders and fund managers preparing investor pitches, and leadership teams who need to present complex strategy with clarity and authority.

We deliver one-on-one executive coaching, board-level specialist workshops, team communication workshops, and keynote presentations across Sydney and nationally.

Why this combination is rare

Most presentation coaches understand either theatrical craft or business context. Jack bridges both. Making 400-year-old Shakespeare feel urgent to a modern audience requires the same skills as making complex strategy compelling to a sceptical board – commanding physical presence, disciplined breath control, strategic use of silence, and precise vocal emphasis. Same pressure. Same techniques. Different context.
