Chief HR, Communications /
Corporate Responsibility Officer

“We feel very lucky to have found Milka and Annette to work with us. They understand how companies work and were immediately able to explain to the people they spoke to how corporate responsibility links to their function and can support them in achieving their objectives. This is a new priority for us and Threefold has given us the achievable and pragmatic approach that we asked for so that everyone can get energised around the impact we can have together. I have truly enjoyed working with these two professionals and I admire a lot their ability to navigate from a strategic view to very hands-on discussions. This is not a given for everyone!"
