Thank you again.” Chris Rauch, Chief Customer Officer, Spryker

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)

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.

Feedback from your session was all excellent.” Jennie Colville, Group Corporate Responsibility Manager, RSA (Royal & Sun Alliance)

"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

“Working with you has been seamless and easy - you actively listened to the specific needs we have at Vestiaire Collective and offered an agenda which perfectly matched the participant’s level of knowledge on mindfulness. There was a perfect balance between theory, science and practice. What I appreciate particularly about the way you deliver your workshops is that you are incredibly strong at explaining topics which may be new concepts to the listeners in a relatable and precise way. It’s very clear that you are an absolute expert on the subject and your credibility contributes to people connecting to the subject easily, even if they never reflected upon it before. Colleagues verbally shared positive feedback on the talk - saying that it helped them become more conscious about which states they are in throughout their (work-)days and learning to appreciate being present.” Victoria Schmierer, Product Manager, Vestiaire Collective

“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

“In our research for mindfulness instructors, we were incredibly lucky to stumble across Ed’s website! Our “Introduction to Mindfulness” workshop was conducted via Zoom, which was very convenient for our International team that is spread across 13 different countries. Ed is a fantastic teacher, he made everyone feel very comfortable and at ease, at the same time making the session engaging and interactive. The team described the session as one of the best training/workshops about self-care and mindfulness that they have ever attended. We would highly recommend Ed’s workshop to any company that would like to enrich their employee wellness initiatives with some nourishment for the mind.” Janina Dowgal, HR & Talent Coordinator at Comdata/Coca-Cola

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
