Alison
Practice Manager
Having started working in a dental practice at the ripe age of 16, Alison saw the importance of great dentistry to a person’s health and confidence through the patients she worked with some time before ever needing a serious procedure done herself. At 18, she had her wisdom teeth removed under sedation and has since used Invisalign to enhance her smile. She regularly whitens her teeth and has 6 monthly dental check-ups and cleans. Alison is the embodiment of what we strive for with our patients at Smiles Matter – a patient who appreciates the philosophy that prevention is better than cure, not only for one’s health but for their self-worth and long-term financial well-being.
Alison’s management of our practice is full-proof. Her relationships with patients, suppliers, consulting specialists and importantly, the rest of the Smiles Matter team are so energetic, professional and forward-thinking that everything runs smoothly and efficiently, as we like it to.
Outside the office, Alison is a wife and mother to a beautiful baby boy, two dog-babies and two cat-babies. She enjoys a beach holiday possibly a little bit more than taking care of her garden and home.
