BSc. (Hons), MSc. (equine studies)

Jennifer originally came to New Zealand, from Scotland to finish her MSc at Massey University, and 11 years later she is still here - and proud to call NZ home. Jen was very fortunate to fall into a clinical trial research role at Massey on completion of her MSc, which was the catalyst for a career across the animal health, dairy and equine industries. She coordinated clinical trials for Veterinary/Animal Health product registration within NZ and Australia for 5 years. One of her favourite roles was with Fonterra for 4.5 years, where she worked very closely with dairy farmers in the nutrition/animal health space. Over the years Jen has had the privilege of working with some of the most amazingly talented, and progressive veterinarians, farmers, consultants and industry leaders, all of which have enriched her knowledge and understanding of these industries.

Jen is extremely passionate about the animal health and veterinary industries. She finds it very rewarding being part of the Gribbles Veterinary team, improving the health and wellbeing of animals (and their owners), in a conscientious and forward thinking manner..

In her spare time you will find Jen doing something active with her friends, riding her horses, skiing, running or in a gym class. She will never lose the travel bug – and every year goes somewhere different.

BVSc. dist, PhD

Lisa graduated from Massey with distinction in 2000 and spent the first 4 years of her veterinary career working in small and mixed practices both here and in the UK. In 2004 she pursued her interest in veterinary pathology into a PhD in leukocyte biology at Murdoch University in Perth, Western Australia. This was followed by 5 years working as a clinical pathologist at the University of Glasgow where she was involved in the day to day running of the clinical pathology laboratory, varied teaching commitments and research projects that ranged from trypanosomiasis in equids, acute phase proteins, feline anaemia and mouse models of leukaemia. Family and lifestyle brought Lisa back to NZ in 2012 where she has been working since this time at the Gribbles Auckland laboratory.

Lisa is interested in all aspects of clinical pathology but particularly enjoys getting involved in CPD and assisting vets and vet nurses to get the most out of their external and in-house laboratory testing. Her large animal veterinarian husband, Brent, has helped her keep a healthy interest in production animal diagnostics and in recent years she has developed a mild obsession with equine endocrinology, completing background work on ACTH testing in NZ for equine Cushing's disease.

Lisa’s spare time is mainly taken up with gardening and running around after children. Personal (and largely unfulfilled) interests include reading, listening to music, horse-riding and golf.
