A Friendly and Caring Staff

In order to provide the highest level of service, a doctor must surround himself with a staff that is not only competent, but unusually warm and friendly. People like this are not easy to find. Dr. Lee feels very fortunate to have attracted such a quality staff. You’ll notice the difference on your first visit!

Taylor Duff- Receptionist

When she isn’t jet setting off around the world, Taylor can be seen at the front desk assisting patients with appointments, answering calls and organising accounts with suppliers. Taylor has been working with us for over 3 years and during that time she was the first person in NSW to receive re-accreditation for the practice and was acknowledged by the Australian Dental Association.

Between working and travelling, Taylor has also been busy with completing a Bachelor of Communications and Media, majoring in Journalism. Now that she is graduated and has some spare time, she enjoys catching up with her friends, binge watching television series and playing with her puppy Lola.

Melissa McCarthy- Receptionist

With over 30 years in the industry under her belt, Melissa can be seen at the front desk assisting patients with appointments and payments as well as answering the ever ringing phone. Melissa’s love for dentistry comes from the experiences she has gained as well as the relationships she has built with patients in helping them overcome their dental concerns and fears.

In the time she has left between commuting from her home on the Central Coast to our practice and to her two daughters in Western Sydney, Melissa enjoys spending time with her family and friends.

Melissa’s bohemian lifestyle is furthered with her love of making candles, creams and ointments, nail painting and pottering in her veggie garden looking for inspiration for a new recipe.

Antonella Vujica –  Dental Assistant/Technician 

A former beauty queen pageant winner, Antonella, affectionately known as Nella has been working at MyHillsDentist since 2012. Not just a pretty face, Nella has also completed her Certificate 3 in Dental Assisting, Certificate 4 in Radiography and a Diploma of Dental Technology. These skills are applied not only in the treatment rooms with the dentists and the patients but also in our laboratory making retainers, mouthguards and whitening trays.

When Nella has some spare time between being a dental assistant, dental technician and a mother of 2 little ones, she loves baking Croatian goodies and socialising with her family and friends.

Nikki Fatseas- Dental Assistant

Although she might be small, Nikki is anything but. This little pocket rocket joined our practice in 2017 and has inspired us with her ability to adapt and learn to this fast paced environment. With only graduating high school in 2016, Nikki has already completed her Certificate 3 in Dental Assisting and hopes to soon undertake her Certificate 4 in Radiology.

Despite only being in the industry for a short time, Nikki hopes for a long and successful career in dentistry, in which she will expand her knowledge to better assist both the Dentists and Oral Health Therapists as well as the patients.

When Nikki isn’t at work, she enjoys travelling, fashion and beauty and eating the flavoursome foods her Greek family creates.
