Dr. Justin Sinfield


Justin has been a Northern Beaches local his whole life and attended Bilgola Plateau Primary School and Pittwater House for high school. He graduated with Honours from the University of Sydney, picking up numerous prizes and awards along the way.  “As a child, I was always using my hands; I loved to draw, design and then create new things. I wanted to be a cartoonist when I was younger, however with my passion for technical problem solving, a keen eye for detail and the ability to utilize my hands, by year 12 my interest had turned firmly towards Dentistry.” Justin is passionate about delivering high-quality affordable dentistry tailored to individual patient’s needs. He is meticulous about his work and enjoys continuing education to both maintain his existing skills and to learn new procedures.

Justin enjoys all areas of general and cosmetic dentistry, with a particular interest in crown and bridge, surgical extractions and implant placement. He takes an ethical approach to his work and believes that information and education are paramount to prevention. Helping patients make informed decisions is important to Justin, as he knows people have different needs and values. He sets himself very high standards when treating his patients and considers how he would like the work performed if it was his own family. He is Invisalign trained, uses the latest WaveOne system for the root canal and has done intensive courses on implant placement.
