Loving all aspects of being a vet nurse, Rachael is also enjoying getting to know all the wonderful patients at Third Ave Vet Surgery. Outside of work she has two small children and a grumpy old cat to keep her busy.

Beth McLeod

Vet Student/Nurse

Beth was born and raised in Brisbane and is currently about halfway through her veterinary science degree at UQ.

With a keen interest in surgery, Beth thoroughly enjoys watching the many different procedures performed at Third Avenue Vet Surgery, learning to relate the knowledge learned in a textbook to real patients.

Beth believes she is lucky to have the unique opportunity to learn from industry professionals, and the chance to work with pets of all shapes and sizes prior to graduating as a vet (although still getting to know the ins and outs of working with cats!).
