Mac Macartney is an author and speaker on values-based leadership. Over a period of twenty years he was mentored by a group of Native Americans, which has deeply influenced his worldview and informs his work with everyone from corporates to communities. He is the founder of Embercombe, a social enterprise located in Devon that seeks to inspire people from all walks of life to contribute their gifts and energy towards a just, peaceful, and sustainable world. Joshua Malkin interviewed Mac about his work and his perspective on wellbeing, leadership and nature.
