James Kyffin, Commercial Director - Animal Health


James graduated with honours from the University of Bristol as a bachelor of veterinary science in 2005.  He spent four and a half years working as a veterinary surgeon in first opinion small animal practice before joining ADM Protexin in 2009.  James has worked as the International Veterinary Manager, Veterinary Technical Manager and Veterinary Director before assuming the role of Commercial Director - Animal Health in March 2020, overseeing the company’s veterinary division.  James is passionate about all aspects of small animal internal medicine but has a particular interest in gastrointestinal disease, urinary health and feline geriatric medicine. 

Outside of work James enjoys a variety of sporting activities including running, cycling, football and Crossfit.  He has a black cat called Hugo who was rescued at the age of three – Hugo has a strong personality but has found the perfect home with James and his partner, Sheila (who is also a vet!)


Liam Gamble, Veterinary Director


Liam graduated from Cambridge University in 2011, before working in a mixed practice in North Yorkshire, where he concentrated on equine medicine and surgery. Liam manages the Veterinary Sales and Technical teams at Protexin Veterinary; working with our teams in the UK, Australia and New Zealand, and our business partners in over 40 countries.

Having spent years owning, competing and working with horses he also supports the equine team and is keen to advance veterinary and owner education in the fields of equine nutrition and probiotics. When not working Liam is most likely walking his dog Tilly somewhere in Yorkshire.


Sophie Nixon, Veterinary Research Manager

After graduating from the University of Liverpool, Sophie worked in a mixed practice in North Yorkshire as a ‘James Herriot’-style vet. Having always been interested in research, Sophie left clinical practice to complete a PhD at the University of Oxford where she studied brain development in humans and animals.

After finishing her PhD Sophie joined ADM Protexin as the Veterinary Research Manager, where her role is to arrange and coordinate research projects that range from product development through to clinical studies. Sophie lives in the Cotswolds with two dogs, Dougie and Rosie, and spends most of her free time renovating her cottage!


Pippa Coupe, Veterinary Product Manager


Pippa graduated from the University of Bristol in 2015. She spent the following five years practicing as a small animal vet in Somerset, and then Buckinghamshire before joining the ADM Protexin Vet team at the end of 2020. Pippa has a keen interest in nutrition, gastrointestinal health and the importance of the microbiota.

Outside of work, Pippa is a keen runner and member of her local CrossFit box. She also enjoys baking and going for long weekend walks with her incredibly lazy Labrador, Ted (who is less enthusiastic about the long walks and would prefer to stay in bed).


Gemma Ives, Veterinary Product Manager

Gemma qualified from the University of Cambridge in 2013. After a couple of months volunteering at a veterinary charity in the Cook Islands, she spent several years working in small animal general practice in Essex and Hampshire. Gemma is passionate about evidence based medicine and is particularly interested in the role that the microbiota can play in so many diseases.

In her free time Gemma loves climbing hills and finding beaches with her terrier, Percy, and hanging out with George the cat (and her husband Ed!). She is a keen cyclist, this year taking on the challenge of cycling the length of the United Kingdom to raise money for VetLife. She also enjoys baking, and was even mad enough to make her own wedding cake.


James Henderson, International Business Manager


After graduating from Cambridge University James went straight into general practice as a small animal vet. James always had a keen interest in nutrition and its role in the treatment of disease, so was thrilled when the opportunity arose to join Protexin.

James manages the international team at Protexin Veterinary; working with our partners in over 40 countries. In his free time he enjoys playing rugby, travelling, and reading.



Rupert Dyhouse, International Technical Manager

Rupert graduated from the University of Liverpool in 2016. After 2 years of mixed practice in mid-Wales, he went on to work and travel as a vet around the mountains and beaches of New Zealand. On returning to the UK he worked with small animals again before then getting back outside as a large animal vet in Warwickshire for 3 years, seeing everything from horses to goats and alpacas (and even the odd tiger).

After drinking fermented mare’s milk with the nomadic shepherds of the Kyrgyzstan steppe he has developed a keen interest in the use of probiotics for both gastrointestinal health and overall immune support.

Rupert lives in Warwickshire and enjoys anything in the outdoors, especially if there is a good dinner at the end of it!
