Our Fellows

We welcome applications from pediatricians who are committed to patient care, education, and scholarship. Successful candidates have completed an accredited pediatric residency program and are eligible for certification by the American Board of Pediatrics. Fellows must become board certified in pediatrics during their fellowship (preferably in the first year) in order to be eligible for sub-specialty certification in Pediatric Endocrinology.

In general, our fellows are excellent clinicians and have been highly rated by Rainbow residents. All fellows enter the program with some interest in pursuing a career in academic medicine and commit to the rigorous research training inherent in our program. Many have had extensive research experience prior to entering the fellowship, though this is not mandatory.
