Dr Marcus Hewitson

Marcus is an experienced General Practitioner and clinic owner at OSNEM, Ocean Shores Nutritional & Environmental Medicine.
He graduated from UNSW in 1998 with an MBBS and Medical Science degree. A generalist at heart, he spent a decade gaining wide experience in rural Australia. Eventually he took his stethoscope to Byron Bay where he settled, attaining RACGP Fellowship in 2009.

In 2011 he fell gravely ill. Despite his years of training and the world’s best medical care, the cause of illness remained elusive. What followed was a journey of discovery into complex illness causation and a long road back to health.
Today he combines comprehensive patient assessment with cutting edge Functional laboratory testing to uncover and address the root cause of disease. He lectures nationally and internationally to medical audiences interested in helping some of their most complex cases.
