Dr David Cahill has been a registered, practicing chiropractor since 1991, in the Malvern East area from 1998. He loves helping people of all ages, from newborn babies and toddlers, to those in their more senior years.

Dr Sarah Rossi

Dr Sarah Rossi has been a chiropractor for 20 years, practising in Australia and the UK. She graduated from RMIT University in 2006 with a double Bachelor’s degree and began her career at Cahill Chiropractic.

David began practicing with a Gonstead approach, and then integrated this with the Thompson technique, to create his own unique blend of gentle, yet extremely effective adjustments. David has always been very active in post-graduate education, continually upskilling in many aspects of chiropractic. He is skilled and comfortable taking care of children.

In recent years, David’s pursuit of excellence in his field has led him to study Biogeometric Integration, a chiropractic approach which he believes honours the body in a most beautiful way.

David currently serves on the Board of the Australian Chiropractors Association, and was President from 2021 to 2024.

He is a past-president of the Australian Spinal Research Foundation, where he spent 11 years serving as a Governor.

In 2026 he was also elected to the Board of the World Federation of Chiropractic, where he represents chiropractic internationally.

David was the chiropractor for the Hawthorn Football Club from 2016 to 2020. He enjoyed taking care of the elite athletes, integrating chiropractic care with the other disciplines in the support team.

David has observed over the years the magnificent potential inherent in every human being, and his passion is to help people manifest that for themselves.

Aside from chiropractic, David loves his two children, Maeve and Finn, his partner Fiona, music, and golf.

In 2011, after 5 years at Cahill Chiropractic, Sarah relocated to the UK, where she furthered her experience working at the London Chiropractic Clinic.

On returning to Australia in 2014, Dr Sarah established her own practice in Sydney, where she continued to care for individuals and families at all stages of life. After becoming a mother to her two boys, Luca and Alex, Sarah has now returned to her home town, bringing her valuable experience, knowledge and a love of chiropractic that has continued throughout her career.
