Henrietta graduated from RVC and initially went into mixed veterinary practice, seeing mostly companion animals. However, as food production was her main interest, she began a Diploma in Veterinary Epidemiology and Public Health and then moved into the poultry industry, working for Slate Hall Veterinary Practice. She then moved into an academic post at the University of Surrey, School of Veterinary Medicine, where she designed and delivered the poultry curriculum. Here, she designed and created the first range of chicken clinical skills models used in UK vet schools, aimed at improving day one skills for graduates entering either commercial or companion industries.

After maternity leave, she returned to education part-time and launched her veterinary practice, Surrey Poultry Vet – the first UK practice to serve only pet poultry. Alongside her practice, she is currently a visiting lecturer at Surrey Vet School, an external lecturer at the University of Liverpool on the RCVS Poultry Certificate, consults for St David’s Poultry Team, is the associate editor (poultry) at the Vet Record journal and collaborates with industry and government on owner and veterinary education. Her particular interest is in responsible antimicrobial prescribing, on which she has collaborated with RCVS Knowledge and the VMD and presented at national conferences.
