Do any of these sound familiar?
✔️ You feel confident in your ideas, but struggle to express them under pressure
✔️ You freeze, fumble, or rush when speaking in front of others
✔️ You want to command the room—but your voice, nerves, or delivery let you down
✔️ You get told to “slow down,” “speak up,” or “relax” and don’t know how
✔️ You’re fine one-on-one, but the moment it’s a group, your presence disappears
✔️ You’ve watched countless videos and read articles, but nothing seems to stick
You’re not alone—and the good news is, this is all trainable.
This isn’t another tips-and-tricks course.
This is a structured, practical training program that builds your speaking ability from the ground up using my proven Three P System:
- Physiology – Learn to use your body and breath as the foundation for confident delivery
- Psychology – Shift your mindset, manage nerves, and speak with clarity under pressure
- Performance – Refine your vocal tone, body language, and delivery to connect with your audience
Together, these three areas cover everything you need to become a grounded, powerful, and authentic public speaker.
You’ll gain:
✔️ Confidence to speak clearly, calmly, and with impact
✔️ The ability to handle nerves and stay present in high-stakes situations
✔️ A stronger, more resonant voice that carries authority
✔️ Body language and presence that support your message
✔️ Practical skills to engage, connect, and persuade any audience
Why This Matters to Me
When I was about eight or nine, a teacher told me I had a terrible voice and shouldn’t sing. I took that to heart. I was already shy, quiet, and navigating a rough home life—bouncing between foster homes while my mum was ill. That comment, from someone in authority, shut me down.
I stopped wanting to be heard. I pulled back from the world.
Growing up in East London in the '80s—with ginger hair, an Irish surname, and a Jehovah’s Witness background—I didn’t fit in. I was the kid who got labelled “a bit of a loner,” and escaped into art and daydreams just to survive. Like many people, I started to disappear inside myself.
At 14, I joined a band. I wasn’t a good singer, but it gave me permission to make noise again. Later, I started voice lessons with an opera and rock coach who helped me unlock something I didn’t know I had. But even when I could sing, I still didn’t like speaking.
That came much later—after I’d worked stressful jobs, hit burnout, and realised I was mumbling so badly I couldn’t even be understood on the phone. I was still hiding.
It wasn’t until I started acting training, speech work, and connecting breath to body that I truly found my voice—not just on stage, but in everyday life. I rebuilt it from the inside out.
And now? I’ve performed live to over four million people. I hold a Master’s degree in acting. I teach workshops and give keynotes on this very subject—how to find and use your voice when it matters most.
But it’s not just about technique. That’s where most public speaking training stops. They’ll show you how to deliver, but not how to believe in what you’re saying. They won’t help you face the inner critic, the fear of being seen, the old voices that told you to stay quiet.
That’s what this course is for.
To help you calm the noise, focus your energy, and find the courage to speak—not like someone else, but like yourself, with presence, clarity, and strength.
We recognise the effort it takes to start and follow through with this training. To mark that achievement, we now offer certification upon completion, providing a tangible acknowledgment of your progress and dedication—not just to your voice, but to yourself.

Frequently Asked Questions
HOW LONG WILL IT TAKE TO IMPROVE MY VOICE?
For some, results are immediate. For others, improvement may take time and can initially feel subtle. Voice work is a gradual process that involves small, consistent changes, ultimately developing into something transformative. With patience and practice, you’ll achieve permanent, lasting results in both voice and communication skills.
HOW WILL THIS TRAINING IMPROVE MY CONFIDENCE?
If you feel nervous about speaking, you might avoid it, which limits practice and reinforces your fear. By making physical changes to your voice and body and practicing regularly, you’ll naturally grow more comfortable using your voice. The more you practice, the more empowered you’ll feel—confidence is a natural result of consistent practice.
Our Public Speaking Mastery course is specifically designed to help you overcome these fears, with dedicated modules and even hypnosis recordings to reshape your perception of public speaking anxiety.
WHICH COURSE SHOULD I START FIRST?
What’s your primary goal? The foundational work in the 8-week course offers essential skills and sets a solid base for any other course. If you’re unsure, this is a great place to start, as it will increase your awareness and control of your voice, body, and breath, essential for effective public speaking and communication.
CAN THESE COURSES HELP ME OVERCOME MY STUTTER?
While voice training may benefit those who stammer or stutter, I recommend consulting a speech pathologist first. They’ll help identify the cause and provide specific treatments tailored to your needs. Our courses can still have a positive impact on your voice and communication skills, but they aren’t specifically designed to treat these conditions.
WHEN DO COURSES START AND FINISH?
Courses start as soon as you enroll and are self-paced, so you decide when to begin and complete them. Each course includes a recommended timeline to help you get the most out of it. Sticking to this timeline encourages steady progress—rushing may reduce benefits, while going too slowly can affect consistency.
HOW LONG DO I HAVE ACCESS TO THE COURSE?
Once enrolled, you’ll have unlimited, lifetime access to the course across all your devices. Choose from a one-time purchase for lifetime access or the “365 subscription” plan, allowing you to start, pause, and complete the course at your own pace.
WILL I RECEIVE A CERTIFICATE?
Yes! Upon completing the course, you’ll receive a certificate to celebrate your achievement. Share it to highlight your new skills, improve job prospects, and showcase your growth in communication and public speaking.
