"As the Dutch saying goes, ‘in times of need, you get to know your friends better’. The past year has certainly been a time of need – a time of crisis, even – for many individuals and organisations around the world. At CHDR, we too have met with our fair share of challenges during 2020. The silver lining is that, like the saying, we have got to know our friends even better: by pulling together in these times of need, we have reinforced the friendships and collaborations, both internal and external, that are vital to our success. Our clients, our scientific partners, our suppliers and our extensive professional networks have all contributed to the way we overcame the challenges posed by the COVID-19 pandemic."
