A selection of testimonials received from private, public and 3rd sector (voluntary) clients

Mac is a born story teller - passionate, authentic, captivating. He weaves seamlessly the ancient wisdom from the indigenous tribes to modern stories of business leaders and teams he has worked with to present a compelling case for the notion that leadership is a choice - a choice that we each can make to align what we do with what we value, and align what we value with what we most deeply and profoundly love. Just like that, Mac brings sustainability home, opens our mind, touches our heart. His wisdom, compassion, and humbleness makes him a great speaker, teacher, and above all, human being that I've had the honour to get to know.

Cindy Tran - Strategy Director at InterbrandHealth, Co-Director of HBSCNY's Career & Professional Development Program.

Mac is a rare person: an inspirational leader, storyteller and thinker who genuinely straddles the business and environmental worlds. He thinks deeply and originally about sustainability at the societal, organisational and personal level. 

I have taken several groups of people to Embercombe and it is invariably a transformational experience for the group. 

If you want to be inspired, go hear him speak. If you want to learn more about yourself, then sign up for a course in Embercombe.

Tom Rippin - Founder of On Purpose

I have co-faciitated development interventions with Mac in several different contexts/cultures and would not hesitate to do so again. Mac has great insight into people and works from the highest level of personal integrity, values and ethics. He models an entirely authentic style of personal leadership which brings great credibility to his work as a developer. Undoubtedly one of the most genuine people I have worked with. Very highly recommended.

Charles Anderson - Head of UNEPFI at United Nations

Mac is a soul and heart opener. He can move people to a greater level of awareness and powerful actions through his high impact words. He can inspire people to be courageous leaders who act on what they believe to be true. Invite Mac to meet your team, and be ready for some powerful change!

Virginie Helias – Procter & Gamble

Mac has remarkable skills and always creates deep impact with the individual's and organisations he works with. If you can persuade him to allocate time to you, you will find it one of the greatest investments you can make.

Mark Drewell - Chief Executive of the Globally Responsible Leadership Initiative

I have known and worked with Tim Macartney for many years. He has been involved in numerous transformation projects with me around the world. His vision about the role of leadership and business in society have transformed all of us and his facilitation and coaching competencies have made all of us better leaders, and more importantly better human beings. Mac is a very wise man. His intellect and his deep intention to serve the world have a profound effect on anyone that gets the gift of being coached by him./ I can strongly recommend anyone who wants to grow to seek involvement with Mac.

Tex Gunning - Unilever

Thank you very much indeed for your contribution to our event. I knew that what you would say would inspire. What I had to leave to chance, was whether the timing and content of what you said would have the right effect on the group at the right moment. As it turned out, your words had an immeasurably powerful effect. Just when, in many conferences, people would be flagging and energy would be tailing off, you lifted everyone with a reaffirmation of the validity of personal convictions. It worked tremendously, and the subsequent feedback session was energised as a result.

Gavin Sanders - Neroche Project Manager, Forestry Commission

Mac Macartney was invited to talk to us as part of a 2-day conference, along with other experts on sustainability and communication. Mac’s interventions were always spot on, inspiring and challenging at the same time. His insights and stories had a very strong impact, helping the P&G audience realise the size of the challenge and giving us hope and confidence in taking action. He is an inspiring, authentic and credible speaker, who can bring a lot of value to any corporation.

Virginie Helias – Procter & Gamble, Global Sustainability Director

Mac has provided profoundly helpful professional counsel to me and to colleagues; and has often presented spell-binding talks for groups embarking on learning at Exeter University. He has also organised and guided a learning event at Embercombe in a way that responded to the emerging, diverse and often unforeseen needs of participants, and which nonetheless reinforced the collective understanding of the challenges we faced. I have no reserve in recommending him, and will happily provide more specific references for anyone considering working with Mac.

Jonathan Gosling - Professor of Leadership, University of Exeter

I would like to thank you for your exceptional input at the conference last week. Your presentation influenced hearts and minds and set the scene for the two days, with many people reflecting back to your thoughts in conversations and workshops.
It was great to hear you speak again and hopefully I will do in the future.

Dr Nick Roberts — UKCEA
