Dr Ronnie Stein



MD 2007 Semmelweis; Cert Spec (Paeds) 2014 Israel; FRACP 2021 - Paediatrics


I’m a Consultant Paediatrician and a Paediatric Endocrinologist. I see paediatric patients of all ages from new-borns, through childhood to the older teens, with a wide variety of hormonal issues.

Children are unique in their needs related to growth and development. In addition, their emotional needs are different from those of adults. Hormone problems, affecting growth, metabolism or sexual development may have a significant effect on emotional and physical well-being. As a paediatric endocrinologist, I am sensitive to these unique needs and work closely with primary care providers, nurses, dieticians, and psychologists to provide kids with the best comprehensive care.
