Philosophy of Care

Dr. Styne understands that complex endocrine conditions in a child may affect the whole family and guides care to include the family unit. As a result of this, he works alongside an excellent team of nurses, dietitians and social workers as the family proceeds through the evaluation and treatment process. He aims to only perform laboratory or radiographic tests when truly indicated so as to spare the child or teenager discomfort and expense. He sees patients on a consistent basis providing continuity of care.

Clinical Interests

Dr. Styne cares for all types of pediatric endocrine conditions in children and teenagers with a particular focus upon obesity, growth disorders, disorders of puberty and diabetes mellitus. Dr. Styne has written a textbook on Pediatric Endocrinology that is used by providers around the world as well as over 100 other medical publications. He is also a leader in the evaluation and treatment of childhood obesity and the complications that arise from it.

Research/Academic Interests

Dr. Styne is considered an authority on puberty, growth and obesity and has numerous publications in these areas and many others. He led the international team that developed new guidelines for the evaluation and treatment of childhood obesity. He has an avid interest in the effects of endocrine disrupting chemicals in the environment on the development of children. While his initial focus was on disorders of growth and puberty, more recently he has turned his attention to childhood obesity and its effects. He is recognized as an outstanding teacher and invited to give presentations across the country and internationally on topics of pediatric endocrinology and obesity.
