After registering as an RVN in 2012, Katie worked as both a surgery nurse and then an emergency and critical care nurse at the Royal Veterinary College referral hospital, where she spent 6 years as a senior ECC nurse. During her time there, she completed her Advanced Nursing Diploma, a Post Graduate Certificate in Veterinary Education, and the Blue Cross Bereavement Certificate.

Katie regularly lectures for VNs, both in the UK and internationally; and has written a few articles, one of which was her own research into sepsis recognition. Since 2019 Katie has been working towards her Advanced Diploma in Psychotherapeutic Counselling, and in spring 2022, Katie started working in a supportive role at The Ralph Veterinary Referral Hospital.

Outside of work Katie volunteers for StreetVet, and she is on the Veterinary Critical Care Nurse Committee which is part of the British Association of Critical Care Nurses.
