Dean Leak's biography

At a glance

  • Olympic performance strategist who supported gold medal-winning teams
  • Trained by Professor Steve Peters (The Chimp Paradox) and UK Special Forces leaders
  • Clients include global organisations such as IBM, LinkedIn, L’Oréal, and Specsavers
Dean Leak is an Olympic performance strategist and international keynote speaker who teaches leaders how to turn tensions into competitive advantages through his Disagreeing Well System™. Dean has worked with Olympic gold medal winning teams, Commanding Officers in the British Army, and senior government advisors. His clients include IBM, LinkedIn, L'Oréal, Baker McKenzie, Specsavers, and Air New Zealand. Trained by Professor Steve Peters, UK Special Forces leaders, and a leading hostage negotiator, he brings insights from elite sport, military operations, and FTSE 100 boardrooms. Dean helps organisations build cultures where people challenge thinking and work through discomfort without damaging trust. His approach combines performance science, behavioural psychology, and practical leadership tools to enable courageous conversation and effective decision-making. Rather than teaching teams to avoid disagreement, Dean shows how to design conflict that drives momentum. This shift transforms high pressure situations from breaking points into breakthroughs, creating environments where innovation and accountability flourish. Audiences learn how to speak up constructively in high-stakes situations, navigate difficult conversations that strengthen rather than fracture relationships, and build psychological safety that supports both challenge and cohesion. Dean delivers practical frameworks that move teams from avoidance to alignment and from politeness to measurable progress. Book Dean to equip your organisation with the skills that separate teams who manage conflict from those who harness it.

Why Imposter Syndrome Is Your Superpower

Can PepTalk help plan the speaker programme for my event?

Yes. Beyond booking a single speaker, PepTalk helps shape a full programme, matching voices to your agenda, audience, and goals across a day or a series. It is a consultative service, not just a booking. Tell us about your event at getapeptalk.com.

What does 'typical fee range' mean?

Speaker fees vary based on factors like event location, format, and availability. The 'typical fee range' figure gives you a baseline of someone's local, in-person rate sits, and we'll confirm the exact fee when you get in touch.

What logistics should I prepare before my speakers arrive?

Before your speakers arrive, confirm AV is tested, a green room is ready, and printed schedules are on hand. Prepare warm introductions for each speaker and brief your team on timings. PepTalk speakers come fully briefed, making event-day logistics smoother and stress-free from the start.

What's the difference between a keynote speaker, an MC, and event entertainment?

A keynote speaker delivers an inspiring or informative talk. An MC hosts and guides the event, keeping things on track. Entertainment — like a band or comedian — creates atmosphere and fun. Each serves a different purpose, and PepTalk can help you book the right talent for all three.

What happens if I need to cancel or reschedule a speaker booking?

Life happens! Most speaker bookings can be rescheduled with reasonable notice. Cancellation terms vary by speaker, but PepTalk handles all the details & contracts transparently upfront so there are no surprises. Our team supports you through any changes, making the process as smooth as possible.

Have all the speakers on the website previously worked with PepTalk?

Not necessarily. While the speakers listed on our website may not have worked with PepTalk in the past, they are recognized professionals in the industry and known to engage in similar events and engagements. Alongside direct talent, we work with a wide variety of speaker agents and talent agencies, to ensure we have the best selection of speakers, hosts, comedians and entertainers available.

What information do I need to provide when booking a comedian?

When booking a comedian, share your event format, audience size and demographics, any sensitive topics to avoid, and the tone you're after. PepTalk makes this easy — their booking process guides you through a simple checklist so nothing gets missed and your comedian is perfectly matched to your crowd.

What information do I need to provide when booking a speaker?

When booking a speaker, you'll need your event date, audience details, format, key objectives, and budget. Having these ready makes the process smooth and straightforward. PepTalk's team uses this information to match you with the perfect speaker quickly and efficiently.

Can I book entertainment and speakers as a package?

Yes! At PepTalk, you can absolutely bundle entertainment and speakers into one seamless package. It's a great way to create a fuller event experience while enjoying simplified booking and better value. Our team handles everything together, making the process effortless for you.

Can I request autographs, personal greetings, signed merchandise, or fan mail from the speakers?

Sorry, we do not accept requests for autographs, signed merchandise, fan mail, or any non-commercial contact with the speakers, comedians or entertainers.

How can I report an issue or make changes to an expert profile?

If you notice something that needs attention or have any queries regarding an expert speaker profile, please email us at experts@getapeptalk.com, and we’ll be happy to assist.

How far in advance should I book a motivational speaker?

Book a motivational speaker at least 3–6 months in advance, especially for popular speakers or large events. Top speakers get booked quickly, so earlier is always better. For major conferences or peak seasons, booking 12 months ahead ensures you secure your first choice.

Help, I need a last-minute speaker for my event!

No problem! We often handle last-minute requests and can secure or replace a speaker, comedian, awards or event host quickly — almost anywhere in the world. However, speaker availability might be limited as the event date approaches. Email hello@getapeptalk.com with your requirements.
