Unlock your potential

Level up your business

With the right public speaking skills, you can build speeches and presentations, and deliver them in a way that makes an impact with your audience. And you will be unstoppable.

Do you want better business results? More effective relationships with your clients? More interest in your company or organization?

Good communication is essential in order to allow people to share their great ideas with others.

“You can have brilliant ideas, but if you can’t get them across, your ideas won’t get you anywhere.”
Lee Iacocca

Each day presents us with the opportunity to engage with the people around us – whether it is establishing relationships with stakeholders, motivating team members, persuading managers or promoting our work to the public.

What we say, and how we say it, matters. With attention spans declining, the challenge to keep audiences focused and engaged has never been greater. But this represents an opportunity for those who can do so.

Do you have what it takes to connect with your audience?

As a CEO, manager, director, entrepreneur or aspiring leader, you must be able to articulate your ideas and convey them in a manner that is clear, compelling and memorable. Being able to communicate effectively is one of the most important skills for achieving professional success.

But ...

How do you stand out when so many others are competing for your audience’s attention?

Do you ...

If you answered yes to any of these questions, you are not alone.

You can be smart, motivated and excellent at what you do, but if you are unable to connect with the audience that you seek to influence, much of your potential will go unfulfilled.

If you can’t structure your speech, maintain the audience’s attention and speak with conviction, you won’t get your message across.

If you seek better business results, more effective relationships, more interest in your company or organization, you need to look at the impact you are making when you speak.

Do you have an important speech or high-stakes presentation, but don’t know where to start?

Do you have a team of talented professionals who need to represent your organization but lack experience when it comes to public speaking?

Are you preparing for a pitch and need to level up your communication?

There is no one-size-fits-all solution. I always work with my clients to create a course that is tailored to their specific needs.

Schedule a free, 30-minute call with me so that we can discuss your needs and objectives and make sure that I am the right person for the job. I never take on a client unless I am 100% confident that I can help them.

And if I am not the right person, I will try to help you find someone who is.

What can you expect from the training or the coaching?

Concrete advice and a lot of practice …

A bit of theory and a bit of practice. A bit of me and a bit of you, back and forth.

There will be writing and speaking exercises, followed by comprehensive feedback. Not only from me but, in group trainings, from the other participants as well. Giving feedback to others helps us reflect on our own speaking.

The amount of time to be spent on any one topic is flexible depending on the length of the training, and more time can be spent on areas of interest.

By building on the knowledge you acquire during the training, you can continuously nurture your public speaking skills further on as well.

After my training or coaching you will:

“There are always three speeches, for every one you actually gave. The one you practiced, the one you gave, and the one you wish you gave.”

John delivered a keynote address about the importance of public speaking to 80 senior members of Gore’s Medical Device Europe team at an important sales event. He was informative, engaging and inspirational. Everyone was motivated to improve their public speaking skills. Following his keynote, John has led public speaking workshops for Gore in Barcelona and Munich. He is an outstanding speaker who thinks carefully about the needs of his audience well before he steps on stage.

I first got in touch with John while preparing to speak at TED Global about my work on ProtonMail. John helped me to sharpen the presentation and get on point faster, making the talk more focused and impactful. My speech was very well received, has since reached almost 1.8 million people and was successful in explaining a complex subject (email encryption) to a general audience.

Andy Yen

CEO, Proton Technologies

John gave the opening keynote on the second day of our unit’s recent offsite in Geneva, addressing an audience of 100+ attendees with a wealth of tips and techniques to deliver powerful, memorable presentations. I applied some of these techniques the very next week in an internal presentation, and I’ve been asked to give that presentation again to senior management, which has NEVER happened before. John is one of the greatest speakers I know and I can recommend his services without reservation.

After a morning of team building activities using improvisation as the conduit, John came on stage to close the staff event which was organised in Chamonix, France. His energy and presence were immediately felt by all the members of staff. The work put into the preparation of his speech was evident and by sharing some his own stories, he was able to conduct a closing inspirational speech which was relevant, powerful and impactful for all at IRU. The whole team left feeling engaged and motivated to tackle the 2019 objectives ahead. Thank you, John.

Secretary General, World Road Transport Organization

I was expecting a few speaking tips and tricks and a few fun exercises, but you went above and beyond – and sideways. You taught me to stand tall. You taught me to anchor myself. You taught me to breathe. You taught me to open up. You taught me to look people in the eye. You taught me to tell the truth. You taught me to walk a mile in someone else’s shoes. I got more than I bargained for in the best possible way.

John gave a brilliant presentation on public speaking during the UN EMERGE programme in Geneva (a two days workshop on leadership development for a group of female staff members working in the UN organizations in Geneva). His talk was inspirational and practical, thanks to the many techniques and tips he shared with the audience. His teaching can dramatically change our public speaking performance and enable us as presenters to have a real and powerful impact. Thank you, John, for your great contribution!

Sara Canna

HR Specialist, World Health Organization

John is a genuine communication innovator. His seminars on gamification of public speaking learning and his interactive Rhetoric game at our conference set the tone for change and improvement in our organisation. The quality of his input, the impact he made with his audience and his effortlessly engaging style made it easy to get on board with his core messages and won over some delegates who were extremely skeptical as to the efficacy of games for learning. I simply cannot recommend him highly enough.

Thomas Scott

National Education Director, Association of Speakers Clubs UK

John joined our Global Sales Meeting in Segovia, Spain and we all participated in his "Improv(e) your Work!" session. I say “all” because it really was all interactive, participatory, learning and enjoyable. The session surprised everybody and was a fresh-air activity that brought a lot of self-reflection and insights to improve trust and confidence in each other inside our team. It´s all about communication and a good manner of speaking!"

Jon Lopez

General Manager Europe, Hayward Industries

Thank you very much for the excellent presentation skills session. The feedback I received was very positive. Everyone enjoyed the good mix of listening to your speech, co-developing a concrete take-away and the personal learning experience. We all feel more devoted to the task ahead, more able to succeed and an elevated team spirit. Delivering this in a short time, both in session and in preparation, is outstanding!

Henning Dehler

CFO European Dairy Supply Chain & Operations, Danone

Thanks to John’s excellent workshop, I have learned many important tips and techniques to become an effective public speaker. John is a fantastic speaker and teacher, with extensive knowledge of the field. His workshop was a great experience and has proven extremely useful for me in my professional and personal life.

Eric Thuillard

Senior Sales Manager, Sunrise Communications

John’s presentation skills training was a terrific investment of my time. I increased my skills in this important area and feel more comfortable when speaking to an audience. John provided the right mix between theory and practice.

Diego Brait

Director of the Jura Region, BKW Energie AG

Be BOLD. Those two words got stuck in my head and in the heads of all those ADP leaders and associates that had the privilege to see John on stage. He was our keynote speaker at our annual convention in Barcelona, and his message still remains! John puts his heart in every word. Few speakers are so credible, humble and yet super strong with large audiences!
