Professional Bio

Hannah Harjén MRCVS is a British small animal veterinarian who lives in Norway. After graduating from the Royal Veterinary College in 2005, she worked in small animal practice and emergency medicine in the UK and Norway, before returning to university in 2017 to do a PhD. She currently teaches the next generation of veterinary students at the Norwegian school of veterinary medicine and researches the effects of snake bites in dogs. Hannah is passionate about veterinary medical communication and has even been known to appear on television to talk about adder bites in dogs.

Hannah grew up on a dairy farm in France before returning to the UK for higher education, and now lives in Norway with her Norwegian husband whom she met at vet school and their two children. Outside of work she is often found hiding in the woods whilst training with the Norwegian search and rescue dog team alongside Otis her Labrador, or middle-distance running.

Hannah’s Pets

Hannah is mum to Otis, a one-year-old Labrador who is in training to be a search and rescue dog and loves nothing more than cuddles and tennis balls. She also provides a home to Turbo the cat who also loves cuddles and hogging the sofa, and Elvis the very vocal guinea pig.

“I love translating complicated concepts into digestible chunks that everyone can understand and benefit from!”
