“David delivered a session for me at Henley Business School Africa... He got a perfect [feedback assessment] score, which is extremely rare. They were blown away… I will gladly use him again and would highly recommend him.”

Marti Janse Van Rensburg

Programme Director, Henley Business School Africa

“This course far exceeded my expectations: it is vastly different to any other training I have been on. The content is well-structured and positively thought-provoking, allowing me to rationalise not only what is actually required when delivering a presentation, but also – and more importantly – the principles underlying influence and persuasion when presenting. My one-on-one coaching session with David was extremely humbling: I learnt a huge amount about myself and my presentation style in an incredibly short space of time. In a world full of numbers, I tend to get caught up in the details. However, this course was most enlightening as it gave me the understanding of where my major areas of development are and how to significantly improve on them, which has enabled me to better come out of my shell. The section on the psychology of the human mind and what content it is most receptive to it was entirely fascinating. I would certainly recommend this course as well as the one-on-one sessions to all who intend to excel within their corporate careers. This course will definitely give you the edge.”

"I have not learnt so much in such a short time as the time spent with David at Henley Business School. His session on presentations and how you actually present yourself completely changed how I will present from now on. I would highly recommend him for any clients. Honestly one of the best – if not the best – session I have ever had during a course. It will really add so much value to my career. Thanks David. Really impressive stuff."

“Thank you, David! Meeting you has unlocked a new level of personal growth for which I am truly grateful. Your programme on making effective presentations was absolutely brilliant. I now understand how to structure my visuals to ensure that I meet the audience needs and present in a way that captivates the audience to the point they forget there's a slide show in the background. Your limitless energy is infectious and makes it really easy to stay captivated and enjoy your programme. Keep up the incredible work that you are doing, and don't stop having fun!”

“David is a delightful, totally engaged presenter and coach. His presentation content is fresh and his delivery concise. I feel more connected when communicating as a result of his one-day course and the follow-up coaching, and I’d highly recommend David for anyone seeking a permanent improvement in their communication skills. During the coaching session, David was an excellent listener. He uses very effective practice tools for you to express yourself, and provides constructive feedback and brilliant tips, with really manageable shifts to make change possible from day one.”


“David is an electrifying public speaker and mentor. Just one day attending a session with David on public speaking and presentation skills gave me a new perspective on the preparation, compilation and execution of a well-structured presentation. His psychometric and personality-based approach to public speaking was insightful: by identifying your personality and aligning it to a celebrity or well-known person, you can create a role model for yourself. Following a role model taught me new skills and exposed me to new ways of communication. I definitely recommend David as a coach and mentor.“

“David!!! Thank you for an amazing presentation that really will help me immensely in my career, as I present often and am required to capture my crowd’s attention while delivering points. You did it with such ease, I felt like I could present when we were done. Thank you for helping me sharpen a skill I hope to use for decades to come!”

“David is an amazing presenter. I was fortunate enough to sit in on one of his presentations. His style of presenting is very unique and entertaining. The thing that really impressed me was his follow-ups in terms of feedback. He delivered on what he promised. I will definitely recommend David, should you require someone to motivate and encourage your staff.“
