The Nursing Team

Cathy Oates

Veterinary Nurse

Cathy comes from a corporate background. She completed a Bachelor of Business Degree twenty odd years ago.  Her and her husband chose to live a bit more and work a bit less as they approached 40 which gave her time to think about what she really wanted to be when she grew up.

She’s been vet nursing part-time ever since. More than ten years on, Cathy still loves her job. Tennis and walking her two children, a Westie named Charly, and Bruce a Mini Schnauzer, keep her pretty busy, but she wouldn’t want it any other way.”

Aaron Edwards

Veterinary Nurse/Puppy preschool leader

My name is Aaron Edwards. I’ve been a part of the Greenfields family since Dec 2018.

My passion for animals has led me to complete my Certificate III in Dog Behaviour and Training and I’m currently studying my Certificate IV in Vet Nursing.

Before I started at Greenfields Vet Hospital  I was an instructor at Moorey’s Martial Arts for 10 years. In my spare time I still love to train and teach martial arts and enjoy learning new skills for my current chosen profession.

I currently have a Rottweiler named Bruce who loves stealing socks from wherever he can, and a Stimpson Python named Madonna.

Karen Gilbert

Head Nurse

Karen originally began her journey at Greenfields Veterinary Hospital back in 2003 when she was in year 12. At this time Karen initially started out here on work experience through school. Through her hard work & dedication she was then generously offered the opportunity to join the team full-time Veterinary Nursing. This then led Karen to complete a traineeship whilst working; in 2006 her Certificate IV in Veterinary Nursing was issued. Karen always knew she wanted to work with animals, so she never looked back!

In 2007 Karen had her first baby, Ella, returning to work on a casual basis seven months later. In 2012 Karen fell pregnant with her second baby, Alex, deciding then to take a break from nursing to take care of her children as a full-time.

In August 2020 Karen decided she’d love to get back into nursing and so returned to us!! She is really enjoying the positive changes, everyday challenges, rewards of Veterinary Nursing again, and working alongside her awesome new team members!

Karen is a local girl enjoying life on a farm with her partner Josh and their children. She enjoys the sunshine, exploring the outdoors, camping, road tripping, cooking, reading, educating herself, listening to music, and generally keeping active and healthy.

Karen doesn’t currently have any pets though knows that one day another doggy will join her family.
