International certification

Mission statement / consulting philosophy

We believe in the virtue of exposure and personal experience. We share a fate of having a balanced experience of line management as well as consultancy. We have been out there. Stood our ground. Taken the heat. And we have honed our skills through working closely with our clients as their trusted process facilitators, advisers, coaches and mentors.

We base our work on a number of different proven methodologies and approaches – in addition to our own performance principles. At the heart of our thinking lies the concept of appreciative inquiry. We believe in the powers of interpersonal communication and dialogue; how people talk has implications for who we become and what we can do as individuals.  We also regard everything in a systemic perspective. Everything is systemic – everything interacts with (affects and is affected by) the things around it – systemic insights into complex situations and problems. We do not deal with the parts of a situation in isolation; we deal with them in concert – both the elements of a situation and how they interact with one another.
