She spent the next two years establishing nursing experience in Brisbane and then took the opportunity to travel. Overseas, Shona worked in various nursing settings, before specialising in surgical theatre nursing at Moorefields Eye Hospital, London.

In 2005 Shona joined a Plastic and Reconstructive Surgeon at his prestigious clinic in central London. It was the start of what has now become her passion. Always wanting to learn about the industry, she attended world renowned conferences including the E.M.A.A. and F.A.C.E. conferences in Paris and London. Shona was also a yearly attendant to the Royal College of Nursing – Aesthetic Nursing Forum.

Passionate about skin care and health, she is a firm believer in encouraging individuals to look the best they can and feel great about themselves.

Shona is also a QLD Clinical Trainer for Galderma (Aesthetic and Corrective).

“I believe that ageing shouldn’t be viewed as a negative aspect of our lives. It can bring wisdom, experience and grace. It is our body’s nature to age, however to soften those effects, and age well, is something achievable to all.”

Under the prescription of Dr Mark Vucak, Shona will see you for your cosmetic non surgical treatments. Friendly and easy to talk to, she is always happy to meet with you, to answer any of your injectable and skin rejuvenation questions.
