Sue Marsh
Clinic Administrator


Sue has a long history of being connected with the equine industry. Her husband was a stud manager, and she spent many seasons helping with overnight foal watches and yearling preparations.


Sue and her husband first met Andrew Argyle as a young veterinarian in Turkey, in 2001. At the time Andrew was their resident vet at the Turkish National Stud. They forged a strong and enduring friendship, which still holds true today.


On returning to Australia, Sue took on the tremendous task of territory manager, whereby she managed over thirty merchandisers in grocery and retail.


In the Winter of 2019, Andrew approached Sue to join Wollondilly Equine. She has become an important part of our team, working as a part time receptionist and clinic administrator. Sue loves the varied nature of the work, the clients and the animals and says that no two days are the same.


Sue has a daughter, a son and three grandchildren (soon to be four). She has a love of gardening, small little woofs and is about to become mum to a gorgeous cavoodle puppy.
