About the chalfont project

At The Chalfont Project, we are architects of change. Our expertise is in the areas of behavioural and social sciences, general management consulting, leadership development, social networking, storytelling and overall organizational development. We are the pioneers of Viral Change, which generates large scale and sustainable culture change in organizations and society.

The Chalfont Project was founded by Leandro Herrero and Caroline Tierney to provide professional services on organizational architecture across industries.

Since its inception, The Chalfont Project has maintained a strong intellectual and pragmatic linkage with the behavioural-social sciences. This background and human-sciences approach is brought to the table in its engagements, coupled with a very pragmatic, results-driven orientation. It is this combination of pragmatism and thought leadership in the behavioural arena that distinguishes The Chalfont Project from other consulting organizations.

The Chalfont Project is a privately owned, limited company registered in England working internationally.
