Dr. Gerald Vargas – Chiropractor


Dr. Gerald, the principal and founding Chiropractor at Essential Health Chiropractic brings his knowledge and passion for functional and integrative Chiropractic care to assist individuals to function at their very best. His motivation and drive to further Chiropractic and natural medicine came from his ow

n health challenges early in life. At 16 years of age, he was diagnosed with a severe inflammatory disorder of the bowel, called Crohn’s disease.

This spurred his own search for solutions to regain his health, which he found through Chiropractic. His passion for working with children and patients with ‘ch

allenging health issues‘ inspires him to continue to do what he does.

Dr. Gerald studied at Sydney University where he obtained his Bachelor of Medical Science Degree. He then went on to receive his Masters of Chiropractic from Macquarie University graduating in 1998.

Following his Chiropractic studies, he then continued his education with training in Acupuncture and Biomesotherapy. In 2003, he travelled to the U.S. to undergo further studies and examination to receive certification in Neuro-Emotional Technique (NET).

During 2006,  he was awarded Advanced Certification in Sacro-Occipital Technic (SOT). He also became certified in the Webster’s Technique, which is a technique which may be helpful for pregnant women throughout pregnancy.

In 2008, Dr. Gerald was awarded by the board of SOTO-Australasia the title of “Certified Craniopath” which is a rare and distinguished honour.

He currently serves on the board of examiners for SOTO-Australasia and is a past-President for the organisation. He is on the teaching committee as a “Primary Educator” for SOTO-Australasia, teaching SOT to Chiropractors both locally and internationally. Gerald is also a regular speaker at SORSI (Sacro-Occipital Research Symposium International) in the USA at their annual international conference.

Dr Melanie was introduced to chiropractic as a child when out of desperation, her parents turned to their local chiropractor to assist in the care of her chronically ill mother when the medical system told her their was nothing else they could do. The change in her mothers health was nothing short of amazing & as a result her entire family started care. Her parents embraced the chiropractic lifestyle & Melanie’s passion for chiropractic was born.

As a mother of five, stepmother of two & grandmother of two, Dr Melanie has a passion for family wellness care. Having lived in the Hills for over 20 years & raised her family here, Dr Melanie loves being able to assist other members of this great community to achieve their health goals & their goals for their family. Being entrusted to care for a child is such an honour that I appreciate daily.

Dr Melanie is thrilled to be working with the team at Essential Health Chiropractic to enable her to continue to provide with love, dedication & passion, the very best of health care to those in The Hills.

DR Jonathan Moore – Chiropractor


Dr Jonathan studied Chiropractic at Macquarie University where he obtained his Bachelor of Science degree, followed by a Masters in Chiropractic, in 1999.

His interest in the impacts of stress on health, paediatrics and neurodevelopment of children has led him to continue his education in this field. This has included completing training in Torque Release Technique (TRT), Sacro-Occipital Technic (SOT), Neuro-Impulse Protocol (NIP), Applied Kinesiology (AK) and Retained Neonatal Reflexes (RNR) protocols. In addition to these, in 2013, he became the first Chiropractor in Australia to be certified as a Craniosacral Therapist (CST), trained through the Upledger Institute.

DR Clara Loh – Chiropractor


Dr Clara studied Chiropractic in Macquarie university where she acquired her Bachelors in Chiropractic Science and then followed by her Masters in Chiropractic Science in 2006. 

Her passion lies in helping families from the young to the elderly. She has furthered her studies in Sacro Occipital Technique and also obtained Certification by the Academy Council of Chiropractic Pediatrics (CACCP). All these helping her to expand her professional ability in adjusting techniques, evaluation and assessment of different stages of development: from pregnancy, birth, infancy throughout childhood.

Her introduction to Chiropractic was through her mother who had a condition which the medical doctors told her that the only solution was surgery but with chiropractic help she has avoided going under the knife and now 20+ years later has not suffered debilitating back pain like she had then. From this, Dr Clara knew that helping people achieve their wellness and health goals required a wholistic and full body approach.

Dr Clara is a mum of 3 young children so family wellness care is definitely top priority for her family and wanting to helping others achieve the same. She and her family are new to the hills area but she was previously helping others for the last 10+years in Western Sydney.

Dr Clara is very excited with this new chapter of her professional career and hope to touch many lives with love together with the team at Essential Health Chiropractic.
