This paper summarises a doctoral research project aimed at advancing professional practice in organisation consulting. I explore what the term 'flourishing' means in a consultant-client relationship, and how such a bond develops. Using a phenomenological methodology (Moustakas, 1994), I draw on conversations with consultants to describe the essence of their experience of flourishing relationships. In contrast to a quantitative analysis, the description obtained in this way retains the complexity of what took place. To summarise their experience, firstly consultant and client mark out some fundamental common ground they have with one another. As they do so, they find effective ways to mutually engage as individuals. With their partnership developing, they also become a dyadic unit 'in relation' (Buber, 1937). Finally, as a team, they act in concert as they engage with the outside world to further the purpose of the consulting assignment for the client organisation.
