Senior Veterinarian/Owner

Dr. Greg Baldwin

BSc, BVSc, MPhil

About Greg

Greg graduated from the University of Queensland Veterinary School in 2002. He spent four years at Eagle Farm Equine Hospital in Brisbane, gathering knowledge and skills in equine medicine, surgery, and racetrack practice.

He then worked at the world-renowned Rossdales and Partners in Newmarket, England, for three years. Here at the thoroughbred training headquarters of Europe, Greg was involved with many of the world’s best thoroughbred trainers and horses. He was able to work with horses owned by the Queen at the Royal Stud, Sandringham, Norfolk, and was lucky enough to meet Her Majesty.

On his return to Australia in 2009, he was employed by Harness Racing Queensland and Racing Queensland as a Veterinary Steward, attending predominantly harness race meetings and assisting stewards with policy and integrity matters.

Greg established The Rivers Equine Vets (formally known as Baldwin Equine) in October 2012 and has built up a loyal clientele over the last few years. From humble beginnings and with the local equine community’s support, the practice now supports two associate veterinarians. We also have an excellent practise manager and reception team.

When time permits, Greg enjoys working on the family farm and spending time with his wife, Kisa, a companion animal vet, and their two young daughters playing the odd round of golf and catching a wave or two.

Greg is passionate about all aspects of equine practice and strives to provide the best possible care for all clients.

Associate Veterinarian

Dr. Matt Mackee


About Matt

Matt is a graduate veterinarian from James Cook University. Matt started his career working for Hawkesbury Equine Veterinary Centre, a busy equine clinic in the Hawkesbury region of Sydney. At the start of 2021, Matt has since started working at The Rivers Equine Vets (formally known as Baldwin Equine).

Born in Sydney and raised in the United Kingdom on a mixed livestock farm and large warmblood stud in the Cotswolds, he has spent his whole life growing up with and working with horses, sheep, and cattle.

Matt returned to Australia in 2013 following 18 months of working and travelling to all corners of the world. Matt’s hobbies include all things sport, whether watching or participating, particularly rugby and, most recently, squash. On his days off, you may find him at the beach or exploring the beautiful hinterland that the area has to offer. He has also recently taken up scuba diving with his partner, Tatum.

We know Matt will be an asset to our region and horse community.


Kisa Baldwin


About Kisa

Kisa graduated from the University of Queensland Veterinary School in 2001 and initially worked in mixed practice in New Zealand before returning to Brisbane and working at the Animal Emergency Centre. Her passion has always been small animal critical care. She worked at Veterinary Specialist Services for many years before travelling with Greg to England, where she continued to work in Emergency and developed her passion for management. On return to Australia, Kisa worked in and managed the Pet Intensive Care Unit at Underwood. Soon after, she took time off to raise her young family and established The Rivers Equine Vets (formally Baldwin Equine Veterinary Services) with Greg in 2012.

Although Kisa does not practice Equine Veterinary Medicine, she is passionate about animal health, continued learning, management, and caring for our team. She currently balances her time between working at Veterinary Specialist Services Carrara and working behind the scenes for us. In addition, she enjoys spending time with her family, walking their three beautiful dogs, and learning to paddleboard.
