David Grove

When you tell others about this work, we request that you credit David Grove for his inspiration in devising Clean Language and Clean Space, and his dedication in honing and developing them over many years. He continues to develop new ways of looking at the way we organise our thinking and perceptions.

Penny Tompkins and James Lawley

No less inspired or dedicated, Penny Tompkins and James Lawley created Symbolic Modelling, bringing David’s genius to a wider audience and adding more than a little of their own. Over 4 years of modelling David, they managed to distil what he does into a form that others can understand and use.

Using their great experience in the world of Neuro-Lingusitic Programming (NLP) and their wide reading in the realms of systems thinking and network theory, they are passionately developing this work still further and are building new frameworks for enhancing our understanding of ‘how we tick’. Whatever they do, they always stay close to the world of ‘clean’ and of modelling.

Penny and James have shown great generosity in directly supporting our learning and development at Clean Change Company. They are an inspiration and a model for all of us in the world of Clean Language and Symbolic Modelling.

Phil Swallow

Co-founder of Small Change Company, the precursor to Clean Change Company, Phil Swallow worked with Wendy Sullivan to develop a large part of the foundation-level training.  He co-trained with Wendy for several years before deciding to start working freelance.  He continues to play an important part in Clean Change Company in a number of ways.  For example, he has built this new and greatly improved website and he generously gives of his time to bounce ideas around, offer suggestions and help me to think through concepts. His creativity, depth of thought and many practical skills are wonderful.
