My name is Claire, I qualified as an RVN in July 2022 after studying a Foundation Degree in Veterinary Nursing at the University of South Wales, based at Coleg Gwent in Usk.

Becky joined the reception team in January 2019.

Hi my name’s Leah and I’ve worked as a receptionist at TVC since early 2019. So glad I got into this line of work as it’s made me realise that I really would love to be a veterinary nurse some day. I now can’t imagine doing anything else. I have a beautiful 2 year old chihuahua named Santos and he loves coming to work with me every day and getting spoilt by all the nurses and vets!


I’m Nikki, I have worked in Treforest Vets since 2017 and you will find me in our Treforest branch.

I am currently a temporary foster carer for a beautiful moggie named Mittens who I have successfully helped to shed quite a lot of excess weight!

I love all animals particularly dogs – the bigger the better!

At the vets I particularly enjoy focusing on helping the nurses and particularly taking pride in creating keepsake pawprints/nose prints and fur clippings for owners who have sadly lost their pets.



I’ve worked as a veterinary receptionist for over 7 years. I have 2 dogs called Twix and Truffle. I also have 2 horses – Beau and Dancer.
My passion is riding and just being around animals. I also love yoga.
I’ve lived in South Wales all my life, but I loved travelling when I used to be an air hostess. Now I like to be at home with my husband and my dogs.


A collie-crazy lady with a love for all animals!

I have two Welsh collies called Newt and Roscoe and a Horse called Buffy (yes, after the Vampire Slayer!) 

I love 80s music, being outdoors, walking the dogs and being out riding. 


Rhys has been on the reception team since late 2021. Before that, he managed a popular and busy hotel but left to work with animals. Rhys doesn’t currently have any pets but can tell the difference between a Dog and a Cat on most occasions.



Jess has been with us since 2022, she’s obsessed with all things furry and will love your pets just like they’re her own. She has two adorable, mischievous dogs of her own (Murphy and Finnegan) and enjoys watching reality tv if she’s not busy cleaning up after them.


I love my job and what I do, helping your pets and serving too.  

I try my best that much is true, I help where I can but I can’t handle poo.
