Dr Ranga’s Story

World of Health has been operating as a family owned business since 1992.
Dr Ranga with his wife, Yaowapa, migrated to Australia in 1991 after completing study and work commitments in the USA.

Our original vision and goal were to serve the local community providing high quality health supplements, reliable advice, and excellent service. It became clear very early on in running the health food store that the community required more extensive assistance with their health concerns. At this point Dr Ranga started seeing clients for health consultations at the store.

Soon the “Return To Wellness” Health Centre was born. With his primary academic and research background in Food and Nutritional Science, Food Microbiology and Safety as well as a strong academic focus in biochemistry, he is competent to assist in finding long lasting solutions to various chronic degenerative health conditions presented by the ever-increasing clients.

Because of his interest in problem solving, he needed to acquire further training not only to strengthen his knowledge of Ayurveda acquired through growing up in a family with a background in Ayurvedic Medicine, but also explore and receive training in novel bio-energetic assessment techniques.

Along with his wife, Dr Ranga’s long-term goal is to open a natural health and wellbeing centre emphasising meditation and mind-body healing for those suffering from cancer and other difficult health conditions.
