Do you offer online learning?
Yes. All our training programmes and executive coaching services are available online. Contact us to arrange a free consultation.
Do you travel internationally?
Absolutely. Share your event details with us and we’ll design a tailored training programme for your location.
How long are your sessions?
Training Courses: From 60 minutes to 3 days, depending on your organisation’s objectives.
Executive Coaching: Typically 1–2 hours per session, with weekly or fortnightly frequency.
Ice Breakers & Energisers: 30–60 minutes, perfect for energising events—ideal for starting the day or boosting post-lunch engagement.
How many people can join a session?
We recommend 10–20 participants for maximum interaction and engagement. Larger groups can be accommodated with multiple sessions or additional coaches.
What happens in a workshop?
Practical Workshops: We begin with a discussion about the skills to be developed, followed by warm-ups and ice breakers. Delegates then work through a mix of solo, pair, and group activities. Reflection, feedback, and discussion are built in throughout, and we conclude with a summary of key takeaways.
Theory-Based Workshops: We start by clarifying the group’s aims, then explore the relevant theory. Participants stay engaged through interactive discussions and activities.
Who have you worked for?
We’ve worked with organisations of all sizes—from start-ups to multi-billion-pound companies—and with people at every level, from apprentices to C-suite executives, worldwide.

What is improvisation?
Improvisation is the skill of making stuff up as you go along. Every human interaction is an unscripted improvisation. Even if you plan your words, the other person’s response will make you adapt in the moment—so why not get better at it? See How we do it for more.
I can’t improvise—can you help?
Absolutely. Improvisation is a skill anyone can learn. Practising it boosts creativity, sharpens adaptability, and builds lasting confidence—all without the need for a comedy or acting background.
I’m terrified of presenting—can you help?
Definitely. Our founder, Dr Alexander McWilliam, is a UK leader in public speaking anxiety, with a PhD in the subject. Through Executive Coaching and our Presenting with Confidence course, we’ll help you transform fear into clarity, presence, and impact.
What is the PSTI®?
The Public Speaking Threats Inventory® (PSTI®) is a 27-item self-report inventory that helps you identify how you respond to public speaking situations. It's grounded in research and designed for personal insight - not diagnosis.
Is it scientifically validated?
Yes, it was developed by Dr Alexander McWilliam et al. (2025) and peer reviewed in Personality and Individual Differences.
Who uses the PSTI®?
Anyone speaking publicly (e.g., students, executives, educators and professionals) looking for targeted insight into their presentation challenges.
