Olivia is currently studying her undergrad in Exercise, Sport & Rehabilitation science at Curtin University. After completing 2 months of her practicum placement at O2 Active, we knew she would be a great addition to our team.

Olivia has always been active (and competitive) from a young age, competing in gymnastics, soccer, netball and her main sport, tennis. Olivia played tennis at an elite level, representing WA on various occasions such as, nationals and Bruce Cup, she has travelled to many tennis academies over the world such as Barcelona Total Tennis and the JC Ferrero Tennis academy, and received the Women’s Division 1 MVP award for Summer Pennants in the whole of WA. Olivia likes the independence that being a tennis player bought her, but also allowing her to maintain a healthy lifestyle throughout her school life which has now continued through to adulthood.

With having experience coaching young (and older) tennis players, Olivia enjoys helping women succeed, feeling confident in their own skin (she’s also a makeup artist – so she is a natural at this!) and most importantly, helping them achieve their goals, whatever they may be!
