I moved to Luxembourg in 2012 without speaking French. The staff at my local Ketterthill lab always switched to English with a smile.
Sarah Patient
I joined Ketterthill as a young technician and I still remember my first day in the lab: the smell of the reagents, the hum of the machines and colleagues who took the time to explain everything. Happy 80th anniversary!
