Bec Lucas

Veterinary Nurse

With a life-long love for animals Bec dreamed of becoming a vet nurse for as long as she can remember. Her life has been filled with animals big and small over the years- dogs, cats, horses, fish, birds, and even a few mice!

Bec lives with her children and shares her home with 2 Labradors, 3 cats and 3 fish.

Deciding it was finally possible to make her dream a reality, she starting her studies in 2019. Bec became qualified in November 2021 and is so excited every day to be living and breathing her dream at Third Avenue Veterinary Surgery as a nurse.

Outside of work Bec enjoys weekends with her pets and children, road trips to the beach or bush, and BBQ’s with friends.

Beth McLeod

Veterinary Assistant

Beth was born and raised in Brisbane and is currently over 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!).

Olivia Byrom

Veterinary Assistant

Olivia is a veterinary science student half way through her degree at UQ and has thoroughly enjoyed the clinical experience she has gained whilst nursing. With the mentorship of the TAVS team, Olivia has developed a keen interest in cytology and soft tissue surgery and enjoys assisting with a wide range of procedures, and getting to know all of our lovely patients and clients.

Olivia has a very naughty rascal of a terrier cross called Luca to keep her busy in between work and study. Outside of work Olivia loves to explore new bush walks and hikes.
