Magdalena andGoc-Ryt
Senior Consultant

Life is a path everyone makes on their own, but what happens if it crosses someone else’s? As a trainer and facilitator for over ten years, my focus has been on supporting people to untangle the complexity of communication and cooperation, and build a path that gives room to everyone in the team, in a variety or organisational structures. In my free time I love venturing outdoors with my husky dog and noticing the subtleties of nature.

My first school had the motto 'Aim High' and that has always resonated with me. I rise to a challenge, both personally & professionally, enjoying new situations and solving difficult & complex problems. I certainly had plenty of those as International Treasurer of Goldman Sachs and as a Director for the London 2012 Olympics & Paralympics. I joined the Board of Impact to help grow the business globally. It's great to be part of such a diverse global team!
