Lorcan Bannon MVDr

Mixed Animal Vet

I come from a family with dairy and equine background so being a mixed animal vet allows me to explore many different aspects of veterinary medicine. I love ophthalmology and new developments of veterinary surgical techniques, it is an area which I have a keen interest. I have no animals of my own at the moment but I hope to have some in the near future.

My favourite celebrity animal is Bugs Bunny.

Holly Roper

Mixed Animal Vet

I love all animals and aspects of veterinary but I am especially interested in small ruminants and flock health. I have had loads of different types of animals over the years, so that is where my interest in animals came from. I love mixed animal veterinary because it allows me to work with all types of animals and it also keeps things interesting. I have one dog, Kanye, who is a Basetthound.

My favourite celebrity animal is ER.
