Susan (Sue) B

Practice Manager

With over 30 years of experience in the veterinary industry, Sue holds both a Certificate IV in Veterinary Nursing and a Certificate IV in Training and Assessing. Her career began immediately after finishing school, gaining hands-on experience in private practice alongside a bird specialist veterinarian before dedicating ten years to the RSPCA, where Sue ultimately served as Head Nurse. This period not only enhanced her clinical expertise but also fostered a lifelong commitment to animal welfare. Sue is a mother of three, grandmother to two, and pet parent to two dogs, Banjo and Max, a cat named Alfie, and a lizard called Zeus. She consistently strives to deliver the highest standard of care to her patients and their families.

Although she found teaching deeply rewarding, her desire for daily engagement with animals and their owners led her back to private practice, where she has successfully managed veterinary teams for the past seven years. Since early 2023, she has been a valued member of the Greencross Wyoming team, collaborating with veterinarians and nurses who share her dedication.

Hi I’m Rhiannon and I’ve always had a deep passion for animals and their well-being from a young age. I knew I wanted to dedicate my life to caring for animals and making a difference in their life through that medicine. 

My journey in veterinary care is driven by a strong commitment to not only helping but advocating for their health comfort and happiness whether it’s preventative care treatment or simply being there to provide compassion I bring my heart into every interaction with both animals and their humans. I’m also a firm believer that learning never stops. I actively seek out new knowledge techniques and advancement in veterinary science to provide the best possible care whether it’s attending workshops courses or staying current with the latest research I’m always working to grow and involved in this ever-changing field.
