Dr Mark Nieh, BDS (Otago, NZ)

Dr Mark graduated from the University of Otago, New Zealand, in 2005. After gaining experience and mentorship in several different dental practices, he decided to open his practice in Hornsby. Fast forward twelve years, the creation and success of Cosmetique Dental Group started, with 8 locations across New South Wales.

Dr Mark is obsessed with restorative and cosmetic dentistry and its never-ending evolution. He always endeavours to make his patient’s experience seamless and perfect.

Sitting in Dr Mark’s chair, you become his number one priority. Dr Mark will only ever recommend dental treatments that he would complete on his own family. He prides himself on delivering perfect results for all his patients.

When consulting with a patient, Dr Mark will always look at restoring the function and aesthetics of a patient’s smile. He believes this is a vital responsibility of being a top-calibre clinician.

He will always talk you through your treatment to keep you informed while relieving any fear or dental anxiety. Providing options after consideration of your current and future treatment needs is also a core value of Dr Mark’s dental philosophy.

He strongly believes in continuing education in any profession. His core interest in professional development in the past decade has been with restorative dentistry involving aesthetic restorations, dental materials research, and implant restorations. He maintains an active account with several prominent overseas research institutes to keep updated on the material research and treatment modalities.

Outside of work, family is important to Dr Mark, especially since having two young children.

Dr April Dubey

Dr. April is a dentist known for her gentleness, meticulous attention to detail, and deeply empathetic approach. Having experienced a traumatic dental journey herself, she understands the fear and vulnerability many patients carry and it’s exactly why she goes above and beyond to make every patient feel safe, informed, and heard.

She takes time to explain every step before it happens, listens carefully to your concerns, and works with you, not just on you. Her gentle, communicative style has helped even the most anxious patients feel at ease in her care.

While Dr. April is highly skilled in all aspects of general dentistry, she has a special passion for aesthetic dentistry. For her, there’s nothing more fulfilling than seeing the transformation not just in someone’s smile but in their confidence and quality of life. That kind of impact, she says, is second to none and it’s what makes her love her profession more every day.
