Dr Tess O’Keeffe

BVSc (hons) MANZCVS (ECC)

Katelyn De Hayr

BAppSc (Vet Technology)

Nursing Manager

Katelyn joined Pet Emergency back in 2016 after graduating her Veterinary Technology degree in 2012 and spending a few years at a general practice clinic. Her and Hannah have been managing our Nursing team since 2020.

After a busy start, she found her passion in emergency nursing. While often very busy and sometimes stressful, she finds it so rewarding to see the patients that are in hospital for long periods of time, or come in very critical, leave happy and healthy with their families. After settling into emergency work, she finds her interests lie in critical care nursing. These are the patients that require the most hands on nursing skills and knowledge and while sometimes challenging, always worthwhile.

In her spare time, she shares her life with her cats, which have all been rescues from her nursing jobs. She also enjoys reading and sleep-ins.


Hannah Eleison

BAppSc (Vet Technology)

Nursing Manager

Hannah began working for Pet Emergency in August 2016 as a junior nurse whilst she completed her Bachelor of Veterinary Technology, which she graduated from in 2017. Alongside her colleague, Katelyn, she has been managing the emergency nursing team since 2020. 

Hannah has a love for the high intensity and fast paced environment that comes with the role and the variety of patients she has been able to care for. She enjoys the unexpected that comes with emergency nursing where no shift is ever the same and having the opportunity to make a positive difference in her patient's lives.

With the wide range of patients that emergency nursing can bring, Hannah has developed a keen interest in critical care nursing and imaging.
