Personal Statement

I was drawn to the field of pediatric endocrinology not only because I found the science fascinating, but because it is a field that offers great continuity of care where I can build lasting relationships with my patients through the crucial years of growth and development. Such a relationship with a child and with his or her family is invaluable and can a make a significant difference in the patient’s care.
