Executive presentation coaching for senior leaders.
I coach senior executives, founders, partners and professional teams preparing to deliver under pressure – board presentations, investor pitches, AGMs, keynotes and the everyday high-stakes communication that defines a leader.
Voice. Presence. Delivery.
Built for the rooms that matter.

Recognise any of these?
Stepping into a more senior role and your voice doesn’t yet command the room.
Preparing for a board presentation and your voice won’t hold up.
Pitching to clients or investors and you can hear yourself rushing.
Building toward a keynote and you want to sound authoritative, not nervous.
Leading a team and your communication needs to land with greater impact.
Preparing for a high-stakes presentation and you want every word to count.
I can help with that.
The voice behind your message
JSG Voice is a boutique executive presentation coaching practice in Sydney. I work one-to-one and with small teams: senior leaders investing in their presence and impact, founders preparing keynotes and investor pitches, partners at law and professional services firms, and creative, marketing and account teams pitching to their clients.
Captivation is technique, not talent. It can be learned.
I coach senior executives, professional services teams and emerging keynote speakers on the most overlooked element of high-stakes communication – the voice. Most presentation coaching focuses on slides and structure. JSG Voice works on the instrument that delivers them: breath, resonance, presence, and pace. The same training I bring to actors at Bell Shakespeare, translated for the boardroom.
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.
Why voice – and why this combination is rare
Most executive presentation coaches work on what you say. JSG Voice works on the instrument that delivers it – your voice. Breath, resonance, pace, weight, presence. The methodology comes from professional voice training and is taught in the world’s leading conservatoires. Almost no coach in Sydney’s corporate market has trained in it.
Add the conservatoire training to a career across acting, copywriting and now executive coaching, and the result is a coach who understands voice as both a physical instrument and a commercial tool. The same techniques used to prepare actors for opening night at Bell Shakespeare, translated for the rooms that matter the most to you.

“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.”
