Duncan is an extremely inspiring speaker who delivered some incredible value at our annual conference. I have seen many speakers in the past and Duncan was by far and away the most engaging and entertaining. Duncan’s keynote is perfect for anyone serious about improving their influencing skills as a leader or for their sales team. I give Duncan my highest recommendation and his book is an excellent read to accompany it too!

I attended one of Duncan’s keynotes “Mastering Effective Influence” before the pandemic with my colleagues and we all took away so much knowledge we could implement immediately. It has already had a massive impact on our successes. Duncan showcased why he is such an authority in the field of influence and persuasion and his Effective Influence Model is a must for all teams to use in their own strategies.

Duncan delivers results. His seminar was one of the most informative and engaging I have attended in the last 8 years of watching speakers and Ted talks. He really knows how to engage the audience and hope to have him back in the future. His live demonstrations of influence and persuasion and on-point case studies and examples really demonstrate why he is in such high demand as a keynote speaker. I would certainly recommend Duncan.
