Dr Vanessa FisherOsteopath

Member of Ostopathy Australia
Learn more about Dr Vanessa
Dr Vanessa Fisher is a highly regarded osteopath who has worked in multi-disciplinary practices in both the UK and Australia for more than a decade.
Originally from the UK, Vanessa graduated from the world renowned British School of Osteopathy (BSO) in London in 2008 with a Bachelor in Osteopathy with Distinction. Vanessa was held in such high esteem at the BSO that she was asked to become a technique tutor in 2010; something Vanessa did until just before emigrating to Australia in 2014.
Vanessa founded The Willow Clinic in Sydney’s Northern Beaches later that same year and treats a wide variety of patients using a combination of osteopathic techniques and myofascial needling. With a dedicated approach to patient care and wellbeing, The Willow Clinic and Vanessa’s reputations are on the rise.
In the past five years Vanessa’s interests in women’s health and paediatrics have grown too; seeing her undertake many post graduate workshops and seminars, focusing on the latest research in tongue-tie, and on the assessment and management of the condition in babies. This has progressed to working with adults who also have tongue-ties, suffer with TMJ dysfunction, speech issues and sleep apnoea.
It is through this developing area of expertise that Vanessa first came into contact with Dr Susan Hsieh and the St George Paediatric Dental Specialists. Vanessa’s role at the clinic is to work alongside the dentists in the preparation for a tongue or lip tie procedure. This can include body work treatment – which is the use of physical therapy and hands-on treatment to release tension in soft tissues, and can be vital in the preparation for a release – as well as post-operative treatment and exercises – which aim to give the patient the best possible short, mid and long-term outcome.
More information about Dr Vanessa Fisher can also be found at https://www.thewillowclinic.
When Vanessa is not being an osteopath she is an equally dedicated mum, and is most likely the one cheering the loudest in the front row of a swim meet, clarinet recital, nippers carnival, AFL or rugby match.
