Executive presentation coaching for Sydney’s boardrooms.
I coach C-suite leaders, board directors and senior partners preparing for board presentations, investor pitches, AGMs and high-stakes keynotes.
Grounded in expert voice technique.
Built for the boardroom.

Recognise any of these?
Presenting to the board next week and your voice won’t hold up.
Pitching to investors and you can hear yourself rushing.
Delivering a keynote and you want to sound authoritative, not nervous.
Chairing an AGM and you’re worried about hostile questions.
Leading a room of partners and you need to command gravitas.
Preparing for media and you want to stay composed under pressure.
I can help with that.
The Boardroom Voice Coach
JSG Voice is a boutique executive presentation coaching practice in Sydney. I work one-to-one and in small groups with the people whose words carry the most weight: CEOs and CFOs preparing for AGMs and investor days, board directors facing difficult meetings, founders raising capital, and senior partners at law firms and professional services firms.
Captivation is technique, not talent. It can be learned.
My methodology draws on the same classical voice pedagogy that trains the actors you see on stage at Bell Shakespeare, the STC and the Sydney Opera House, translated, sharpened and made commercially useful for the boardroom. Linklater. Rodenburg. Berry. Houseman. Fitzmaurice. Clinical voice science mixed with years of professional application.
No yoga mats. No motivational fluff. No confidence tricks. Rigorous, kinaesthetic, evidence-based voice and presence work for people whose reputations are made and unmade in rooms of ten.

“Jack is a superb speaking and presentation coach. He distils the technical gems from his vast experience in the arts and as voice coach and turns it into something that is readily accessible for the corporate setting.
I highly recommend Jack for anyone who has specific speaking engagements coming up, or simply wants a highly skilled professional in your corner to help you level up more generally.
From a most grateful corporate professional, 2024.”
