Martin Roberts

Just a brief note to thank you again for the excellent job you did in moderating this event and indeed helping make it the best yet – ‘excellent’ was also how the vast majority of the delegates rated you on their feed-back forms.

You did a great job linking all the presentations using both gravitas and humour. You also got the panel session buzzing which I suspect we could have run for another hour without losing the momentum.

I look forward to working with you next year….

“Ayesha gave us some real and no-punches-pulled insight into Labour and politics more widely, which is something you don’t hear that often at a corporate gig. She managed to make everyone laugh while maintaining a serious presentation. She is also a very uplifting presence on stage, if that makes sense. I’m a big fan and expected her to be good – but she was superb. Feedback from the audience has been uniformly excellent.”

"Joe made a group of hesitant people think outside of their comfort zone with ease. He took real-world examples and applied them to the talk. If I have any regrets it’s that we didn’t get more time with him.”

“I needed someone that would provide an ‘instant cocktail’ that would address multiple issues: change management and transformational leadership. I still do not believe how lucky I was to that Buddha, Joe Britto. He was a ‘great refresher’. He provided the right combination of theoretical knowledge and practical tips for dealing with transformational change.”
