Dr Catherine Chow

Dr Catherine Chow


Dr Catherine knows a visit to the dentist can make people a little nervous, which is why she takes a gentle, comforting approach to dentistry. After graduating with Honours from the University of Queensland and working in rural South Australia, Dr Catherine returned home to Queensland in 2019 to begin work at Greenland Dental. She has loved working with the team in a relaxed environment ever since and focuses on providing conservative treatment and the long-term maintenance of a healthy smile.

When Dr Catherine isn’t busy treating patients, you might find her working away in the kitchen with some baking. Always searching for interesting new recipes, Dr Catherine brings in the results to test out on the team, proving that dentists can sometimes be sweet tooths too!

Dr Catherine also enjoys spending time with family and friends, delving into photography or travelling – particularly to places with very cold winters in contrast to her beloved Brisbane during summer.

Dr Bianca Chai


Dr Bianca has called Brisbane home for the past eight years after graduating with Honours in Dental Science from the University of Queensland. Dr Bianca left her childhood home of Malaysia to pursue tertiary education in Australia, and she loves every bit of her time in the Sunshine State.

Dr Bianca is passionate about helping her patients live a high quality of life through dental care. Improving and increasing awareness of oral health among her patients is something Dr Bianca does each day, taking time to clearly communicate treatment options and welcoming any questions her patients may have. Dr Bianca is known for her warm and gentle nature, and she ensures her patients feel comfortable and relaxed during every visit.

Outside of work, you can find Bianca keeping busy with a range of activities at her local church, catching up with friends or enjoying her time off at home. One of Dr Bianca’s hidden talents is speaking fluent English and Mandarin.

Dr Lina

Dr Lina Zhou


Dr Lina has been working with Greenland Dental since late 2021 and has quickly become a trusted practitioner with our patients. A proud local North-sider, Dr Lina completed her dental training at the University of Queensland, graduating with a Bachelor of Dental Science with Honours. She firmly believes prevention is always better than cure and strives to practice minimally invasive dentistry.

You will find she takes the time to help patients improve their self-care routine and only provides necessary treatment. Her gentle and pain-free approach makes her lovable by any patient, young or old. Dr Lina can also speak Mandarin fluently to service those who are more comfortable with speaking Mandarin. When not in the clinic, Dr Lina will be making art, gardening, or dancing to all kinds of music.

Dr Eliza Chen


Since graduating with Honours from the University of Queensland with a Bachelor of Dental Science, Dr Eliza has set out to provide a pleasant experience for every patient she cares for. With a friendly manner and gentle approach, Dr Eliza believes preventative care and oral health education are central to her work as a dentist. Dr Eliza’s special interest areas in dentistry include oral surgery, children’s dental care and aesthetic dentistry.

Outside the clinic, Dr Eliza enjoys spending time with family and friends and is a big vegetarian foodie who is always trying new recipes. Dr Eliza also loves listening to music and is fluent in English, Mandarin and Taiwanese – a skill that is harder to master than you might think!

Caitlin Gallagher

Caitlin Gallagher

Practice Manager

When a family friend recommended applying for a role as a dental assistant, Caitlin wasn’t sure it would be the right fit for her. Fast forward more than six years to today, and Caitlin absolutely loves the world of dentistry. Caitlin has experienced most facets of the practice and enjoys learning new things and taking on new responsibilities.

Caitlin particularly loves working with an array of different people and learning new things – it’s definitely a job she is never bored in because no two days are the same. Helping patients become more comfortable visiting the dentist and getting to know regular patients is a key reason Caitlin loves her job at Greenland Dental.

Apart from being super organised (A very important quality in her role as Practice Manager!), Caitlin enjoys camping trips, staying active and spending time with her family.

Emily Hudson

Dental Assistant

Emily has been a valued team member at Greenland Dental in the role of Dental Assistant since 2019. While studying at university, she enjoyed learning about the human body and is very happy that she gets to work in a career that allows her to continue to do that. The most rewarding aspect of Emily’s job is seeing how her contribution to the care of patients helps others. She also revels in the fast-paced environment of the clinic, which always keeps her busy.

Outside of work, Emily spends a lot of time with her significant other and family and loves to eat out for dinner and lunches with them. In fact, if you have any local restaurant or café recommendations, please let Emily know! She also likes to bake sweets (and eat them), finding the cooking process very therapeutic and a good way to wind down after a busy day at the practice. Apart from baking, Emily spends time looking after five little quails at home, along with gardening – in fact,she’s content spending time potting up new additions to her plant collection.

Lillyana Wareham

Lillyana Wareham

Dental Assistant

Delving into the many interesting areas of dental nursing and making patients feel at ease are just some of the reasons Lillyana loves working at Greenland Dental. She’s our resident smart-cookie, having just begun a dual degree in science and mathematics at the University of Queensland, Lillyana would love to study astrophysics and quantum mechanics. She finds learning new things fun, and one of the aspects of dental assisting she enjoys the most is predicting what the dentist might need next which makes the appointments flow smoothly from start to finish.

Lillyana loves reading and all forms of art, and as you can probably tell from her university studies she has a passion for learning, specifically about the body and science. Hanging out with friends and family is also important to her when at work or studying.

Courtney Forsyth

Dental Assistant

After joining our Greenland Dental team, Courtney has found her passion as a dental assistant. She thoroughly enjoys the variety that each day brings, and delights in learning new things along the way.

After many years in the hospitality industry, Courtney was yearning to learn something new and thought dental assisting was the perfect way to kickstart her career in the health care industry. She really appreciates working in a supportive and encouraging environment and feels like she is a part of a big family when working alongside her colleagues. Working at Greenland Dental, she feels as though she can truly perform at her best when helping her patients, which is the highlight of her role. Being able to improve others’ smiles and help deliver emergency care where needed is a rewarding and motivating aspect of Courtney’s role as a dental assistant, and one that she looks forward to each day.

Courtney values her time with loved ones, and so outside of the clinic, she spends most of her time making memories with friends and family. She’s a talented artist and quite outdoorsy. She loves a weekend away camping in the Queensland bush and going on thrilling motorbike rides.

Tia Siemienowicz

Tia is a dental assistant at Greenland Dental. She has been an assistant for over a year. Meeting new people is one of Tia’s favourite aspects of her job. She has a sweet and warm manner and has the ability to make all our patients feel at ease. Tia understands that the dentist is not the funnest place to be so she endeavours to create a calm and stress-free atmosphere for each and every one of our patients.  

Tia is currently studying to be a nurse. She loves learning new things and her role here at Greenland Dental perfectly complements her healthcare studies.  

In her spare time, you’ll find Tia keeping fit at the gym and spending quality time with her family and friends.

Liarna Robinson

Liarna Robinson

Dental Assistant

Liarna started her dental assisting journey with us in June of 2022 and has since settled in nicely as our newest member of the Greenland Dental family. The unique nature of the position as well as the variety in each day is what initially enticed Liarna to test the waters as a dental assistant. With a keen and enthusiastic mindset, she has flourished in learning all aspects of her job and eagerly takes on a challenge. 

Liarna looks forward to making meaningful changes to everyday lives and strives to ensure her patients feel comfortable during their visit. With her easy-going nature, she is someone you will instantly enjoy talking to and trust to have by your side.   

In her own time, you can almost certainly find Liarna outdoors. Whether it be at the beach or in the bush, being surrounded by nature is where she enjoys most of her time. She lives by the sentiment that life is better with friends and takes every chance to spend her free time with those dearest to her.


Dogtor of Fluffy Cuddles

Ollie is our four-legged receptionist here at Greenland Dental. He is working hard learning how to be Chief of our Welcoming Committee.

Ollie consistently demonstrates enthusiasm and zest for his work, sharing his love and fluffiness with everyone he meets. Although, at times he can be caught napping on the job (being cute is tiring!!… don’t you know?).

Ollie can be found behind the front desk during the day. Being a cavoodle, he is hypoallergenic and does not shed fur. This makes it easy for us to comply with our strict infection control protocols needed to be an accredited dental practice.

He is at our clinic almost every day putting our patients at ease. Let us know if you would like to say hi when you attend your next appointment!

Outside of work, some of Ollie’s favourite things to do are walkies, chewing on his favourite stuffed toys and last but not least… eating (he sure does love his treatos!).

Chantelle Wardrop

I have just had my first appointment at Greenland Dental. WOW! What a great team. From the reception staff to treating staff, they were all such a pleasure.
Dr Catherine was very thorough, not only working on the tooth I was there to receive treatment on, but identifying some other problematic teeth and providing options for future treatment. I will definitely be returning for future procedures.
