Ed was a great pleasure to work with. He was easy to get hold of for up-front conversations, very open to discussion of the format of the event – and most importantly delivered a fantastic talk exactly as promised with great content and expertly handled audience participants and Q&A session." Mark Williamson, Action for Happiness.

“Ed is an engaging and knowledgeable speaker, and his talk proved extremely popular amongst staff, who turned out in numbers to listen to him. He shared his wealth of knowledge and personal experiences of mindfulness in a way that highlighted the practical relevance of research to everyday workplace experience. Ed combines a relaxed and easygoing approach with thoughtful professionalism. I would highly recommend him.” Carmen Martinez, UNICEF UK

“I just wanted to send a little note to say a big, big thank you for being so brilliant this weekend. Everyone seemed to really enjoy and be inspired by your stories and tips, which is exactly what we were hoping for. And especially thank you for kicking off the festival’s talks – not the easiest job, but you packed out the yurt. Hopefully now we’ll have a new group of people going off and looking in to mindfulness and feeling a bit better on a day-to-day basis.” Clemmie Nettlefold, UK PR Manager, Innocent Drinks (following talk given at Innocent Unplugged Festival)

"Ed delivered a great session on mindfulness, which he pitched at the right level for those who had practised mindfulness before and for complete beginners. It was great that we were able to experience the practical application in the session too. Ed was really easy to work with, very accommodating, interactive with the group and clearly passionate about his work. It was a really enjoyable and very informative session that everyone enjoyed attending.” Claudia Donaldson, Legal Services, Sainsbury's

"From the outset I was confident that Ed was the right trainer for TBWA. Ed's deep understanding of Mindfulness together with his appreciation of the impact the Agency's dynamic, creative and unpredictable working environment can have on our people, combined with his calming and patient personal style was an ideal match for the Agency. It was an absolute pleasure to work with Ed." Helen Doughty, HR Director,TBWA/London

"I just wanted to say a personal thank you to you for your Mindfulness session at our Health and Wellbeing Week. To be honest, I didn’t really know what to expect but have come away feeling enlightened and very much interested in finding out more about the art of mindfulness and how I can focus on being in the moment with purpose, curiosity and compassion. Feedback from your session was all excellent.” Jennie Colville, Group Corporate Responsibility Manager, RSA (Royal & Sun Alliance)

The participants found your session extremely engaging. You gave a really good insight into mindfulness and the fact that some of the doubters recognised the benefits showed how much of an impact you made. Excellent in all categories, and it was a pleasure working with you.” Perry Funnell, Organisational Development Consultant, University College London.

Your feedback was just wonderful, as I knew it would be." Kirsty Buck, Head of Programming, Learning, Guardian News and Media

The session was fantastic and we've had brilliant feedback. Lots of people left their phones on their desks this lunchtime too, which was a great start to practicing what they had learnt!” Esme de Courcy, People Manager, Future Foundation

"It (the eight-week mindfulness course) was a journey into the unknown for us - and one very worthwhile in completing. During an unparalleled time of change, uncertainty and risk, it has provided, at the very least, a weekly grounding, but for many, including myself, I believe it has made us more personally enlightened and planted seeds of habitual thinking and practice that will continue to influence us as we move forward with our lives. This is powerful stuff – expertly delivered – thank you!" Lloyd Murphy, Headteacher, Wray Common School, Reigate

“The recent mindfulness sessions were incredibly well received by our UK. and Irish employees. Given the recent outbreak of the Covid-19 crisis, I have no doubt that the insights shared by Ed will have a positive and lasting impact on all who attended. Thank you for delivering such a practical and thought provoking talk. The feedback has been exceptional and many have asked for a recording of the talk.” Chris Collins, HR and Customer Experience Director, Intrum

The whole experience was very positive. Ed was a really great presenter and his presentation was perfect for beginners of working with mindfulness as well as those who had previously done so before. All the feedback we have had has been very positive and the participants enjoyed all elements of the presentation.” Amy Greenham, Lawyers on Demand

Ed Halliwell is a fantastic workshop leader who really understands how to get the attention of the crowd and be both educational as well as entertaining. The atmosphere he created in his workshop was fantastic and people really felt held to try new skills while at the event. People commented on the accessibility of what was presented and their willingness to come back again on following days (the workshop was held over three days at the same time each day). Thank you for a really inspiring workshop – we would love to work together again.”Jana Stefanovska, Founder/Director, NOW Live Events

We recognised that if we were going to attract our target audience to the event, we had to secure a national speaker with some gravitas. It is with great fortune that we managed to secure the services of Ed. Ed was our keynote speaker and lived up to his billing - his presentation was informative, enjoyable, thought-provoking and delivered in a professional and engaging manner. Our post-event evaluation confirmed that the presentation was a huge success.” Ian Burnitt, Local Interest Group For Mindfulness, Hull and East Riding of Yorkshire NHS

Ed has worked with the full-time MBA students at Imperial College Business School for three consecutive years. We have been deeply impressed by the way in which he brings alive the practice of mindfulness for a professional, and often sceptical, audience. Ed is a confident and competent facilitator who we will no doubt bring back into our classrooms.” Dr Charles Donovan, Principal Teaching Fellow, Imperial Business School

Ed, your session at the Althorp Literary Festival was just brilliant – thank you so much for it. Earl Spencer
