Exclusive Speechwriting for Exceptional Leaders
AI can generate words. But true leaders need a voice.
I craft speeches that inspire, persuade and leave a legacy.
Exceptional leaders stand apart.
So should their words.
I’m Brent Kerrigan, an executive speechwriter and communications expert based in Geneva, specializing in professional speechwriting services for CEOs, international leaders and their communications teams.
I craft bespoke speeches that capture your unique voice, aligning with your leadership communication strategies — so you don’t just speak; you lead the conversation.
Forget generic, AI-generated scripts. Your message deserves clarity, strategy, and storytelling that moves people to action.
Where do you stand?
Here’s the difference…
Most services provide words. I provide influence through tailored executive speechwriting and strategic messaging.
Big communications firms treat speechwriting as an afterthought — an “add-on” to their services.
They churn out generic keynote speeches, templated talking points and forgettable messaging. They write for the masses. I write for you.
Your leadership isn’t off-the-shelf. Your speeches shouldn’t be either.
Every word should reflect your vision, values and leadership style — not a prepackaged formula.
On high-stakes issues — climate action, sustainability, policy, leadership — you can’t afford to sound like everyone else. You need messaging that is authentic, precise and impossible to ignore.
Because exceptional leaders don’t sound like everyone else.

A few quotes I’ve co-created…
António Guterres, UN Secretary-General, Petersberg Climate Summit, 2020
“These are dark days, but they are not without hope.”
Patricia Espinosa, Executive Secretary, UNFCCC, 5th Anniversary of the Paris Agreement
“The Paris Agreement is a covenant of hope with humanity.”
Patricia Espinosa, Executive Secretary, UNFCCC, One Planet Summit
“Trying to address climate change at current financing levels is like walking into a Category 5 hurricane protected by only an umbrella.”
Patricia Espinosa, Executive Secretary, UNFCCC, Address to the Vatican
“If we truly want to make the fundamental, transformative changes necessary to address climate change, perhaps what we need is not a physical ark, but an ark of ambition.”
I don’t work with
just anyone
I specialize in partnering with exceptional leaders who understand that their words shape their legacy, including:
CEOs & Business Leaders – Delivering impactful speeches that articulate vision, inspire teams, and influence industries — particularly for those speaking English as a second language.
Government Officials, Diplomats & Multilateral Leaders – Crafting speeches that shape policy, engage international audiences and drive diplomatic and institutional conversations.
Sustainability, NGO And Climate Leaders – Elevating critical messages on climate action, biodiversity, ocean conservation, and global sustainability efforts.
Your leadership deserves more than an AI-generated, generic script.
