About Us

Our Veterinarians

Dr James Tiernan


James was raised in country Queensland. After growing up with lots of pets, becoming a veterinarian was a natural progression for James.

Following graduation with a Veterinary Science degree from the University of Queensland in 2001 James moved to the UK and worked in several busy small animal clinics dealing with dogs, cats, and many other small furry patients that are common in the UK such as rabbits, guinea pigs, hamsters, gerbils, rats, mice and birds. Whilst in the UK James successfully passed examinations in a General Practitioner Certificate in Small Animal Medicine [GPCert (SAM)] through the European School of Veterinary Postgraduate Studies. This was extremely useful in helping James to further build his skills in small animal medicine.

After spending eight years in the UK, James returned to Australia with Jane. On returning to Australia, James spent a short period of time at the University of Queensland Veterinary Small Animal Hospital before moving to Victoria and starting employment at the Western Animal Emergency Centre based at Werribee which is part of the Melbourne University Veterinary Hospital in 2009.

In June 2010 James and Jane were very excited to take over ownership of the Highton Veterinary clinic; it had long been their dream to have their own clinic. They have enjoyed working with the very capable staff and meeting all the clients and their pets.

James’ main interest is mostly in small animal medicine, especially emergency medicine. He also has a soft spot for cats (particularly British Short Hairs) and loves Cavalier King Charles Spaniels. 

Outside of work James keeps busy with his young children Seamus, Niamh, Aislin and Declan and enjoys cycling and getting to the gym when he can. His pets Paddy & Fergus, as well as his kids birds, and fish keep him busy.

At the clinic you can see James for just about anything related to your pets health, but in particular general medicine and emergency cases, as well as all pocket pets.

And after winning the hearts of our nurse Sarah and then-receptionist Caitlyn, she never really left – nobody can recall exactly why except that we all loved her beautiful calm nature and sweet little face.  Hmmm!….what happened we ask for Betsy is the reason we sometimes have “discounted ” pre-sampled bags of food for sale in the clinic, the bigger the better for Betsy! As she never stops eating, she has since been banned from access to all food areas of the clinic.  

So now you won’t see Betsy in the blue reception area, but if you come in the green door, she won’t be far, just sleeping her days away in the admin office.
