Who we are

We are a group of senior global public health and communication professionals who have spent years working to solve some of the world’s toughest health and development challenges. Our knowledge and experience in social and behaviour change communications has helped bring the world to the edge of polio eradication, end the West African Ebola Outbreak and protect vulnerable communities from natural disasters and climate change. 

Together we have lived and worked in more than 20 countries including Nigeria, India, Pakistan, Sri Lanka, Maldives, Morocco, Honduras, Afghanistan, Indonesia, Jordan, Vietnam, Angola, Sudan, Sierra Leone, Somalia, Poland, Ukraine, Romania, Switzerland, Canada and the United States. 

In the end, it's all about people. We believe human behaviour is ultimately what spreads and stops disease, and what drives human progress. Understanding what motivates people to act positively is to understand how we can make the world a more just and connected place.
