Our Culture Makes the Difference

Our People: Kate Krontz

"If I had a motto, it would be: Learn from your mistakes and say, ‘What next?’ I am Kate Krontz and I am a Laboratory Research Technician II here at Charles River. I do a lot of flow cytometry and cell-based assays, and in English, that means I take a clients drug and see what happens in mice. We’re letting clients know how their drug is working with the cancer that they are trying to fight. Usually, whenever I tell someone, for the first time what I do, it is always a reaction of, ‘Wow! You are working in cancer research.’
