About Us

Big River Health Clinic

Big River Health Clinic was originally established by Dr Ken Dewar Chiropractor/Osteopath and was later joined by Physiotherapist Jenny Drewitt-Smith. This health clinic has been servicing the Grafton and Clarence Valley community for over thirty years. 

The clinic is set in a cottage style home with an old world charm. There is wheelchair access and 4 treatment rooms. 

Our friendly staff are very welcoming and the clinic has an unquestionable homely feel about it. 

We are available to take appointments Monday to Friday.

In 2019 when Ken and Jenny retired,  Dr Hugh Giles, Osteopath took over the role as owner/director of Big River Health Clinic. Locally born and raised in Grafton, Dr Giles is keen to help his community improve their wellbeing.

Jenny Kullas is a Chiropractor with 12 years experience in the field and has recently joined the team at Big River Health Clinic. 

Previous owner/director in a clinic of her own in Cairns Queensland, she is very enthusiastic to help the community of Grafton achieve their health goals.

Mark Pilkie, an Osteopath from Sydney has recently relocated to the area and is eager to assist the community with his skills.

All three practitioners look forward to providing the same service to the community that has been so valuable over the last 30 years.

About Osteopathy

Originally founded in 1892 it was the American physician Dr Andrew Taylor Still who brought Osteopathy into the world. He believed that the body possessed everything it needed to maintain health, it was only in the absence of correct functioning that these inherent capacities were unable to nourish and heal the body. Osteopathy is the art and science of using manual contact with the application of knowledge and experience to diagnose and treat a body that is in a state of dysfunction, using its own physiological mechanisms to assist in bringing it back into a state of normal functioning. To put it simply Osteopathy aims to help your body do what it is trying to do naturally.  


Osteopathic treatment is based on the application of the tenets. that;
-the body is a dynamic functional unit;
-the body possesses self-regulating and self-healing mechanisms and;
-structure and function are interrelated.


Osteopathy also acknowledges the importance of health being interdependent on body, mind and spirit and that all these aspects need to be addressed in order to have well rounded health.  

Osteopathy draws on a wide range of techniques soft tissue, mobilization, articulation, stretching, balancing and cranio-sacral work to best suit the individual patient for their individual presentation.

About Chiropractic

The word ‘Chiropractic’ comes from the Greek words cheir (meaning ‘hand’) and praktos (meaning ‘done’), i.e. Done by Hand. The name was chosen by the developer of Chiropractic, Daniel David Palmer.

A prolific reader of all things scientific, DD Palmer realized that although various forms of manipulation had been used for hundreds if not thousands of years, no one had developed a philosophical or scientific rationale to explain their effects. Palmer’s major contribution to the health field was therefore the codification of the philosophy, art and science of Chiropractic which was based on his extensive study of anatomy and physiology. 


Palmer performed the initial Chiropractic adjustment in September 1895. Palmer examined a janitor who had become deaf 17 years prior after he felt something “give” in his back. Palmer examined the area and gave a crude “adjustment” to what was felt to be a misplaced vertebra in the upper back. The janitor then observed that his hearing improved.

From that first adjustment, DD Palmer continued to develop Chiropractic and in 1897 established the Palmer School of Cure, now known as the Palmer College of Chiropractic, in Davenport, Iowa, where it remains today.
