About Mark

I’m Mark, aka That Guy in Blue. Trainer, speaker, event host… and a flat white lover through and through. For over twenty years, I’ve been helping people grow in who they are and what they do. As a trainer, as a coach, and now as a “presentologist.” I didn’t start this work because I love the spotlight. I know exactly how nerve-racking it can be to stand there. How your heart can pound, your mind goes blank, and your hands feel just a little too clammy.

That’s why I started Presenters Lab. A place where you’re free to experiment, where you might stumble and where you’ll definitely rise again. I see it as a presentation studio that helps you tell your story the way it’s meant to be told: in your way.

So that, in the end, you feel at home on any stage. Big or small.

Speak-in

Just a moment to spar, ask questions, or practice.

Sometimes you don’t need a full training. Just someone to look over your shoulder. Whether you’re stuck in a story, unsure about your structure, nervous for a presentation, or simply looking for a fresh perspective. That’s what the Speak-in is for.

An accessible, free drop-in moment where you can spar one-on-one with Mark about anything related to speaking and presenting.

Mark has the unique gift of improving your public speaking skills in record time. His approach is practical, with plenty of room to practice in a safe setting. With just small tweaks to your story, he shows the difference instantly. The training immediately made me a better storyteller, and now I approach every speaking opportunity with confidence.

Richard de Veer, Director Corporate Solutions, Just Eat

We did an inspiration session with Mark. In just 90 minutes, he shares practical tips and insights that are incredibly valuable. Even after this short time, I already felt I had taken a step forward. Just imagine what he can achieve with you in a two-day workshop… that’s something I definitely want to experience as well.

Paul de Metter, CTO Experience, Conclusion

The variety during the two-day training sparked rapid growth. And even though the stage already felt familiar to me, with every step I felt more empowered — as if Mark kept placing a new step for me to climb. As a trainer, he stands right beside you: motivating, inspiring, and fully present for every participant.

Presenting isn’t a talent, it’s a muscle you train. During the training, I said: “I’m just not feeling it right now, so many ideas and yet it all feels blank.” Mark replied: “But even what you’re telling me now is a story.” That stuck with me. A story doesn’t have to be perfect as long as it’s real.

Ilse ten Brinke, Corporate IT Recruiter, DataVisual

The most important lesson? It all comes down to your Message in a Bottle. Mine: Mark is a damn good trainer. He listens, inspires, and fills you with confidence. I was nervous, but I’m so glad I didn’t turn back. Two days of pure growth and enjoyment. Want to become a better speaker or presenter? Call Mark.

Orlando Belfor, Recruitment advisor, Ministry of Health, Welfare and Sport

During this interactive training, we were challenged as participants to improve our presentation skills. This training is a must-have for anyone who wants to learn public speaking or work on their presentation skills. I’ve taken many trainings throughout my career, but I’ve rarely had a trainer with as much passion and drive as Mark. I would definitely recommend this training.
