She brings this knowledge and experience to NIVH, as well as her interest in animal welfare, health and behaviour.  Dr Sarah lives locally with her husband and new baby son Bodhi and outside of being a vet, she has an amazing musical background and an interest in sailing, camping, bush walking, mountain biking and yoga.

Dr Sharon Tan BSc BVSc 


Dr Sharon graduated from the University of Sydney in 2006 though she had previously obtained a degree in Conservation Biology in Canada before deciding to pursue her dream of veterinary science in Australia. She returns to the workforce after a year on maternity leave with a renewed passion for all areas of clinical practice and endeavours to be a well-rounded general practitioner.  Dr Sharon is thrilled to be joining the very capable NIVH team and is looking forward to meeting our wonderful clients. 

When not at work,  Dr Sharon is mum to two kids and a Devon Rex who loves a smooch. She loves hiking and swimming, but would very much prefer to be chilling with Netflix or enjoying a good meal these days.

Rebecca Geloven

Veterinary Nurse and Practice Manager

I have worked as a veterinary nurse since 2000 at several local hospitals, an emergency centre in Sydney and in the UK. I have a special interest in medical nursing, radiology and animal behaviour and am currently studying Certificate IV in Companion Animal Services with The Delta Society, which focuses on training and behaviour. I am a local girl with a young family and two fur babies -15 year old Leroy, a Border Terrier, and 10 year old Huey, a cross breed. I enjoy spending time at the beach, going on holidays and being with family and friends.

Jenna O'Brien

Veterinary Nurse

I have been a veterinary nurse for over 20 years and still love it as much as the day I started. I love working with both the clients and their fur  babies, forming the best relationships with both to create the best care possible.

My career began with a love for wildlife care and rehabilitation starting out as a zookeeper at Symbio Wildlife Park.

When not at work I am kept very busy with three small human children, a galah called Jack and a cattle dog x staffy called Juno.

Abbie Lovell

Veterinary Nurse


I have been working in the veterinary industry since 2017 and recently completed my Certificate IV in Veterinary nursing at Yallah TAFE.  With a love for all creatures great and small, it was after  my move from the UK to Australia that I embarked on a lifelong dream to become a veterinary nurse.  Previously I was a human sports therapist with a keen interest in rehabilitation.  With my two qualifications my passion is to give every patient the best quality of life, with my specific areas of interest being orthopaedic rehabilitation, weight loss and geriatric care.  I am also mum to two human daughters and three cocker spaniels and a keen soccer player!


Tegan Macdonald

Veterinary Nurse

After starting with NIVH as a casual veterinary nurse I have recently joined the team on a regular basis. I have worked locally as a nurse for 10 years and still love it just as much as the day I started. I have also studied zoo keeping but my heart has always been set on veterinary nursing. I have a special interest in surgery, behaviour and care of neonates. Things I love about my job are no two days are ever the same, you never know what you will be caring for next. I love being able to make a difference to our clients and patients through the care they receive from us. We have a great, passionate team at NIVH and I'm very proud to be part of it. When I'm not working I'm kept busy looking after my 2 young kids and 4 fur kids, as well as 2 birds and Franklin the turtle.  

Jess Adams

Veterinary Nurse

I have worked as a veterinary nurse in the Illawarra since I was 15 years old, graduating with my Certificate IV in Veterinary nursing in 2010. My passion has always been with all animals great and small and I find huge rewards working with them and their owners knowing I'm making a difference. I have a special interest in surgical and medical cases but love every day on the job and couldn't imagine doing anything different.

My family includes myself, my partner Richie and my daughter Keeley. We also have 3 dogs; Diesel, Axel and Ruby and a cat named Chevy. On our days off we all love spending time outdoors camping, exploring new places and getting away for weekend fun! 

Sarah Godfrey

Veterinary Nurse

I started volunteering with the NIVH team in 2019 while studying my Certificate IV in Veterinary Nursing at Yallah TAFE. I have always had a passion for caring for animals and knew that I would be happiest when working with them. Since graduating in December 2020, I now work as a veterinary nurse at NIVH where I am always learning something new and each day is unique.

The NIVH team is incredibly supportive and we are all like a big family, and I am very grateful to part of it. In my free time, I spend time with my partner and our two miniature dachshunds, Martini and Chaser, who are always keen for an outdoor adventure.
