Our Veterinarians


Dr Mark Simpson

Dr Mark Simpson

Dr Mark grew up in a family that had an insatiable appetite for natural history.  There were animals, and stories about animals, filling every day.  So it was no surprise when a very young Mark declared his desire to be an “animal doctor”.

Mark graduated from Sydney University in 1991, and began working in the Newcastle region.  He met his soulmate, Kate, and they began building the Sugarloaf Animal Hospital in the mid nineties.  Since that time he has overseen the growth of Sugarloaf Animal Hospital and leads the practice and profession in the philosophy of excellence in evidence-based veterinary practice.

Mark has pursued continuing professional development and achieved his Membership of the Australian College of Veterinary Scientists in 2001.  He is a regular speaker at avian and herpetological societies, as well as presenting at avian and unusual pet veterinary conferences.

Mark, Kate, and their children share their house and their lives with a floating population of pets, including the cats Laura Bananas, Mr Pink, and Megan, not to mention the fish, frogs, lizards, snakes and turtles.  When he is not looking after the health of animals, Mark loves the beauty and complexity of the Australian bush, and spends as much time as possible enjoying its serenity!

Richard with Benghazi the Bearded Dragon

Hailing from Malaysia, Dr. Richard graduated from the University of Sydney with first class honours, and decided that joining the team at Sugarloaf Animal Hospital was an opportunity he couldn’t miss.

Having worked in the hospital as part of his clinical rotations, he fell in love with the variety of patients that are seen in the hospital, as well as the amazing team that forms the backbone of Sugarloaf Animal Hospital.

As part of his final year thesis, Richard has done research on Pacific oysters and Ostreid Herpesvirus-1 which led to a published peer-reviewed paper in Aquaculture, an internationally acclaimed scientific journal.

Richard’s veterinary interest include surgery, aquatic, and exotic animal medicine. He also hopes that being able to speak English, Mandarin, Cantonese, and Malay will help communication with clients of different backgrounds.

During his holidays, he goes back to Malaysia to visit his four Dobermanns, Bingo, Kopi, Browny and Dolly, his freshwater fish tank containing mainly guppies, and Koi fishes in his family’s small pond.  Away from work, Richard likes to travel and experience different cultures.  At home, he likes to cook and bake, pampering people around him from time to time.
