Piper Goldie
M. Clinical Ex. Phys. & B. Ex. & Sports Sc.Piper completed her Master of Clinical Exercise Physiology (EP) and bachelor’s degree in Exercise and Sport Science at Deakin University, Melbourne. She has experience in private practise, inpatient/outpatient hospital services, and elite sport. This is where she discovered how exercise can be a powerful tool for the treatment and management of chronic health conditions. EP appealed to Piper as exercise is one of the few clinical treatments that is undisputedly supported by the literature. It is for this reason that she is so enthusiastic about facilitating exercise and passing on her knowledge to clients.
Piper has always enjoyed exercising, specifically resistance training, running, and hiking. Her passion is something she wishes to share with all her clients. She believes that everyone should have the knowledge and empowerment to be able to achieve their own health and exercise related goals. Piper will ensure that you are comfortable, supported, and challenged in a way that is conducive to your long-term objectives. She loves to see people achieve their goals and make progress that they did not think possible regardless of their diagnosis.
In her previous role, Piper enjoyed working in a multi-disciplinary private practise alongside Physiotherapists, Exercise Physiologists, and Exercise Scientists. It is for this reason that she was drawn to the integrated model that Healthfix provides. Collaborating with professionals from all health domains consistently provides amazing learning opportunities.
