Insights & guides
Have you ever listened to an executive whose English wasn’t perfect, yet everyone in the room trusted what they had to say?
Now think about someone with excellent grammar who struggled to hold the audience’s attention.
The difference wasn’t language proficiency.
It was credibility.
In international business, credibility is one of the most valuable professional assets you can develop. It shapes whether colleagues trust your recommendations, whether clients believe your expertise, and whether leaders see you as someone ready for greater responsibility.
Many professionals assume that credibility comes from speaking flawless English.
It doesn’t.
Research on public speaking shows that audiences evaluate speakers based not only on what they know, but also on how they communicate that knowledge. Confidence, preparation, body language, supporting evidence, and audience engagement all contribute to perceptions of credibility (Harvard Division of Continuing Education, 2025).
In other words, credibility is not simply about speaking English.
It is about communicating in a way that inspires trust.
One of the most surprising aspects of communication is how quickly people form impressions.
Before you’ve explained your first idea, your audience has already noticed:
These non-verbal cues answer an important psychological question:
“Should I trust this person?”
Aristotle described credibility (ethos) as one of the three foundations of persuasion. He argued that audiences are persuaded not only by evidence, but also by the perceived character and competence of the speaker (Aristotle, trans. 2007).
More than two thousand years later, the principle remains remarkably relevant.
Executives who appear calm, prepared, and intentional immediately increase their perceived credibility.
One of the clearest differences between experienced leaders and less experienced professionals is the language they choose.
Many professionals unintentionally weaken their authority by softening every recommendation. For example:
While these phrases are polite, they also introduce uncertainty.
Executive communicators replace hesitation with ownership. Instead, they say:
These small linguistic changes communicate confidence without sounding arrogant. As Duarte (2012) explains, persuasive communication depends on helping audiences make decisions, not simply presenting information.
Leadership is often communicated through language long before it is recognised through job titles.
Many professionals believe sounding intelligent means using sophisticated vocabulary.
In reality, the opposite is often true.
The most credible executives explain difficult concepts simply.
This isn’t because their ideas are simple.
It’s because they understand their audience.
Research in cognitive psychology demonstrates that people process information more effectively when unnecessary mental effort is reduced. Messages that are clear, structured, and concise are easier to understand, remember, and act upon (Sweller, 1988).
Clarity communicates confidence.
Confusion creates doubt.
Credible professionals don’t expect people to believe them simply because they hold an important position.
They support their recommendations.
Instead of relying solely on opinion, they use:
Evidence reduces uncertainty.
Stories strengthen connection.
Together, they make recommendations more persuasive.
Harvard’s guidance on public speaking similarly emphasises that speakers strengthen credibility by demonstrating preparation, citing evidence, and showing why they are qualified to speak on a topic (Harvard Division of Continuing Education, 2025).
Confidence is often misunderstood.
It is not speaking louder.
It is not dominating conversations.
It is not pretending to know everything.
True executive confidence is communicated through deliberate behaviour. Confident professionals:
These behaviours signal composure.
Composure builds trust.
Trust builds credibility.
In global business, credibility depends on more than language.
It also depends on cultural awareness.
Different cultures interpret confidence differently. Highly direct communication may be appreciated in one country but perceived as confrontational in another. Likewise, a communication style intended to show respect may unintentionally appear uncertain elsewhere.
Canale and Swain (1980) argue that successful communication requires more than grammatical knowledge. Professionals must also develop sociolinguistic competence, the ability to adapt communication to different audiences, situations, and cultural expectations.
The most effective global communicators don’t simply speak English well.
They communicate appropriately for the audience in front of them.
Many professionals admire executives who appear naturally confident.
The reality is usually different.
Behind every calm presentation are hours of preparation. Experienced communicators prepare far beyond vocabulary.
Preparation reduces uncertainty.
Reduced uncertainty creates confidence.
Confidence strengthens credibility.
You cannot tell people you are credible.
You demonstrate it.
Every recommendation you make, every meeting you lead, every presentation you deliver, and every conversation you have either strengthens or weakens how others perceive you.
Fortunately, credibility is not something people are born with.
It is built through consistent communication habits.
These are the qualities that make executives influential, regardless of whether English is their first language.
Communication Audit
Have you ever wondered how your communication is perceived by colleagues, clients or senior leaders?
The Communication Audit provides a personalised evaluation of your executive presence, persuasive language, presentation structure, confidence, cross-cultural communication and overall communication effectiveness. Rather than focusing solely on grammar, the audit identifies the communication habits that influence how others perceive your expertise, so you can communicate with greater credibility and impact.
About the Communication Audit15–30 minutes. English or German. Online worldwide.
Short answers to what most people want to know before booking.
Each engagement has a starting price, agreed with you before any work begins.
What moves the price is how much work happens outside the live sessions. Every engagement can also be booked in a lighter form, which costs less.
Rehearsal only. We use the call to practise material you have already written. No document review, research or written feedback beforehand.
Sessions only. For the Intensive and the Partnership, we work live in the sessions, without document review or preparation between them.
The full versions include the work I do between sessions: reviewing your draft, researching your audience, refining the structure, and written feedback. We agree the exact price in the free consultation, once I know what you actually need.
That depends on which engagement, and most of all on how much time there is before the moment you are preparing for.
Communication Audit. A week before your deadline is ideal. That leaves comfortable time to review your material, send the report, and rehearse before you deliver it.
Presentation Intensive. Two to three weeks works best, so the sessions can be spaced out properly rather than compressed at the last minute.
Communication Partnership. This one is ongoing, month to month. Most of the value builds over several months rather than in a single cycle.
If your timing is tighter than this, do get in touch anyway. It is often still possible.
Most people are more ready for this than they think.
You will get the most from the work if you can already hold a conversation in English, because we focus on how you use the language rather than teaching it from the beginning.
If your English is solid but not yet fluent, the Communication Partnership is often the best fit. It gives us time to build business vocabulary alongside structure, delivery and confidence, rather than preparing for a single event.
If you are not sure where you stand, the free consultation will make that clear very quickly, and you are most welcome to book one.
Not quite, though the two are easily confused.
I do not teach English from the ground up. Instead, we work on how you use the English you already have when it counts: how a presentation is structured, how a recommendation is made, which words carry authority, and how you handle the questions that follow.
You bring the expertise and the language. My work is making sure both of them land.
Online, over Google Meet. You will receive the link with your booking confirmation, and there is nothing to install.
Yes, and it is a good way to start. If your material is already written and you would simply like to practise delivering it, you can book the session time on its own.
There is no document review, research or written feedback beforehand, so it costs less than a full Audit or Intensive.
For a larger team, or for something more structured than a rehearsal, tell me what you are preparing for and I will come back with a price.
Yes, very happily. If a team is presenting together, or several colleagues are preparing for the same kind of moment, the rehearsal can be run as a group.
It works best with a small group, so that everyone gets real feedback rather than simply a turn to speak. It also tends to work best within one team, since you will be watching each other rehearse.
For a larger team, or for something more structured than a rehearsal, do tell me what you are preparing for and I will come back with a price.
Yes. The booking calendar shows my availability in your time zone as well as mine, so there is never confusion about when we are meeting.
My clients work across Europe, the Americas and beyond, so times outside standard European hours can usually be arranged.
A relaxed conversation of 15 to 30 minutes over Google Meet. It is not a test, and there is no need to prepare perfect English.
The call is there so I can understand what you are working on, rather than to begin the work itself, so we will not be doing any coaching or preparation in it.
I will ask a little about your role, your goals and the challenge in front of you. Towards the end I explain how I could help and answer anything you would like to ask, including about price.
There is no obligation to book afterwards, and the call is free either way. If you would like to get more out of it, there is a short guide on how to prepare.
Not at all. The consultation is simply there if you would like to talk things through before committing, and most people find it useful.
If you already know what you need, you are very welcome to book directly:
Please do say so, and as early as feels right. It is genuinely useful to know.
In most cases it means we are focusing on the wrong thing, and that is mine to put right rather than yours. A change of approach is usually all it takes.
If it still is not working after that, I would far rather tell you honestly than carry on regardless. The Partnership runs month to month with no lock-in, so you are free to stop at the end of any month.
Of course, and many clients are funded by their employer.
I invoice you, and you pass the invoice on to your company. It names the engagement only, so what we actually work on stays between the two of us.
Completely. Nothing you share with me is passed on to anyone else.
Your documents are never shared with anyone else. Protecting your material is central to this work rather than an afterthought.
Very little, because very little is collected. This website has no analytics, no cookies and no tracking of any kind, so reading it leaves no trace with me at all.
What I hold is what you send me: your booking details, our correspondence, and the materials we work on together. None of it is sold or shared for marketing.
The full detail, including how long I keep things and how to ask me to delete them, is in the privacy notice.
The free consultation can be in German or English, whichever feels more comfortable for you.
The coaching itself takes place in English, since English is where you need to perform. If something is easier to explain in German, we switch for a moment and then carry on.
Life happens, and moving a session is never a problem. A message as early as you can manage is all I need.
To move a session to another time in the same week, four hours’ notice is plenty. To cancel, or to move it beyond the current week, twelve hours’ notice.
Inside those windows I do have to charge for the session, simply because the time has already been set aside for you. If something unavoidable comes up, please do just talk to me.
