Pediatric endocrinology at WashU provides a robust training experience where fellows are regularly exposed to common and rare endocrine conditions. Highlights include fellows' continuity clinic where fellows have their own schedules and follow their own patients over 3 years, rotations in specialty clinics beginning in the 1st year, support for clinical or basic science research with a mentor of the fellow's choice from any department at WashU, and outstanding, supportive faculty and staff.
