I just wanted to thank you so much for such a wonderful experience you gave us this morning and say how much my colleagues at ING benefited from your wisdom. It was a tour de force and I am deeply grateful to you and look forward to working with you again sooner rather than later.

Academy for Chief Executives

We have used Greg to coach us for two major one-off project presentations and a one-to-one interview. We were successful in winning all three commissions. We have also used him to run an in-house presentational skills workshop. We have found his training very helpful and effective. It has been enjoyable! I am sure we will use him again.


Well delivered course, extremely engaging and would highly recommend it to all staff.

Arup PPM

Expectations exceeded. Simple, effective, takeaway lessons that can be implemented straightaway, but make a big difference in effectiveness and communication delivery.
The course met my expectations. Fantastic tutor: energetic, knowledgeable and engaging, thanks!

Booz Allen Hamilton

Greg has worked with several Channel Four reporters and presenters, both experienced professionals and people new to broadcasting. He has achieved significant improvements in a short time and given them good ideas as to how to work on developing their skills further. I’ve been really pleased with his work and everyone he has helped has also told me how much they enjoyed and valued the experience.

Your talk to our students at their introductory weekend is one of the most important in the programme and as ever you made the most of the short time allocated to the subject. As was evident from the applause you received at the end, your pearls of wisdom were much appreciated and I’m sure they will remember your invaluable advice.

Transformational course. You should write the book – the House of Commons would benefit from it!


I feel so much more confident and feel I can prepare and deliver talks more effectively. Greg is a very dynamic, charismatic communicator.

The course covered the most important aspects of presenting with detailed breakdown on how to communicate PowerPoint.

Medical Advice and Communication Specialist with Jansen Biologics, Leiden

Thank you for all of your help over the last few months. I feel a noticeable difference in the power of my voice which in turn has provided me with greater confidence when speaking in public. I am also finding the breathing techniques a great help in controlling my nerves both before and when speaking.

Greg really made us feel comfortable and was very positive and encouraging to all. Many thanks. Everyone should access this training. It has been excellent.

NHS, Southampton

Thank you for a great day – I benefitted tremendously. The presentations that I made last week were definitely better than before and I got positive feedback from the audience. I would certainly recommend your voice training to colleagues who make regular presentations – how to unlock the power of your own voice through breathing and posture was a revelation, and adds a new dimension to delivering presentations with conviction and presence.
