Principal Veterinarian

David is the principal veterinarian of Thornleigh Veterinary Hospital.
Throughout his career he has gained tremendous knowledge and experience working in some of the largest veterinary hospitals in Australia.
After graduating with a Bachelor of Veterinary science with first class honours from the University of Sydney in 2003, he started full time work at the RSPCA in Yagoona, gaining a large exposure to a vast array of different cases, and animals great and small, before joining the team at Sylvania Veterinary Hospital in March 2005. From 2003 to 2006, David also worked part time at the veterinary emergency and critical care units of the Animal Referral Hospital, and the North Shore Veterinary Specialist Centre, alongside some of Australia's leading veterinary specialists.
David has an interest in bird medicine, and completed a one year course in Avian Medicine with the Post Graduate Society in 2007. In 2008, he was inducted as a Member of the Australian College of Veterinary Specialists after successfully passing examinations in the subject area of Avian Health. He is also a Member of the Association of Avian Veterinarians Australian Committee.
David has also furthered his disiplines in all aspects of small animal practice, completing one year distance education courses in Ultrasonography and Oncology through the Post Graduate Foundation of the University of Sydney. In 2009 he was awarded a Masters of Veterinary studies in Small Animal Medicine and Surgery from Murdoch University, in recognition of 4 years of further study. In the same year he recieved further accolades, successfully passing membership examinations of the Australian College of Veterinary Scientists in Small Animal Medicine.
When he can tear himself away from the practice, he enjoys family time with his wife Berena, and his two gorgeous children; daughter Jelena, and son Aiden. Also, we can't forget his cheeky Labrador Mango, and chirpy Banana, a rescued Indian Ringneck.


Dr Caitlin McQuarrie


Caitlin was born and raised on the Central Coast. Becoming a veterinarian was the only career she could ever think of, deciding back in primary school, and working hard to get accepted into the course. After high school, she attended University of Sydney where she finally achieved her dream and completed her Bachelor of Veterinary Science.

During her vet school, she volunteered in South Africa with community dogs and Laos where she worked for the Department of Livestock and Fisheries on improving cattle production. These fantastic opportunities help foster a passion for helping those less fortunate and a desire to continue taking part in out-reach programs in the future.

When not at work Caitlin enjoys swimming at the local pool or reading a good book in one of her favourite cafes. At home, she is often found in front of her sewing machine or with a pair of knitting needles in hand. Whilst she doesn’t have any pets of her own now, she dreams of rescuing a small pack of greyhounds in the near future.

Nikki Menner
Cert IV VN

Veterinary Nurse


Nikki is one of our experienced nurses, and has been at Thornleigh Veterinary Hospital since 2010. She has completed her certificate IV in veterinary nursing, and the hospital continues to benefit from her experience and knowledge.

The great feature that Nikki loves about working at Thornleigh Veterinary Hospital is the close interaction that she can enjoy with the clients and their beloved pets. She really loves the hands-on work involved in and around the clinic, and has particular interests in clinical pathology, surgery, and dentistry.

Nikki is always seeking opportunities to learn more, and hence provide a better standard of care for our pets. She has a can-do attitude and works well under pressure, keeping the whole team calm and focused.

Away from the practice, she enjoys anything to do with arts and crafts, including painting and sketching, as well as exercise. Nikki is a pet parent for Poppy, a cheeky, chatty but very affectionate Plum Head Parakeet, and an English Staffy named Rambo.

Kristy Fleming
Cert IV VN

Veterinary Nurse

Kristy is one of our experienced vet nurses and has been at Thornleigh Veterinary Hospital since 2011. She completed her veterinary nursing certificate IV in early 2009, having known from the age of 6 that she always wanted to work with animals.

Kristy enjoys the surgical aspects of the job and loves nursing animals to recovery and back to health. Kristy also gains great enjoyment in working with the Ku-ring Gai Shelter, as she finds it very fulfilling to find animals their 'furever' homes.

At home, Kristy has four animals of her own, all rescue animals. Her cat 'Mischief' is a troublesome tabby cat who plays fetch and is learning to play the piano! There's energetic 'Yogi', a Staffordshire who is a constant bundle of fun. And we can't forget 'Onyx' and 'Raven', who are sisters that came from the shelter, that Kristy couldn't bear to separate.

Away from the practice Kristy loves snowboarding and unicycling, which she taught herself to do, and now competes in the National Unicycling Competition in a variety of disciplines. She also has a fondness for baking and is learning how to decorate cakes.

Rebecca Arbuz

Veterinary Nurse

Rebecca is one of our weekend veterinary nurses, who is always ready to put her hand up to help out during the week when required. She is in the final year of her Masters of Chiropractic Science at Macquarie University.

She has a real menagerie of pets-8 in fact! Two dogs, one cat, one rabbit, three chooks and one galah! They all keep her very busy and amused at home.

When away from the practice... well, is she ever away from the practice? She will be the first to admit that even on her days off, she can be seen hanging around the practice cuddling a furry friend or interacting with the other members of staff.
