In the third episode of HuffPost Greece's video series 'Greeks Gone West,' we introduce Constantine A. Stratakis, M.D. D.Sc., a tenured investigator in the NICHD, who has been the head of the Section on Genetics and Endocrinology (SEGEN) since its inception in 1999.

His work is focused on treating the rare condition of 'gigantism.'

The research began with a family who came to the the U.S. National Institutes of Health for treatment for gigantism in the mid-1990s. In that family, the mother and two of her sons all had the condition.

This is his story.
