Personal Statement:
Adolescent medicine presents the opportunity for physicians to help guide patients through an often challenging time as children transition into adulthood. It is easy to be overwhelmed by this period of life, which is what I want to help with the most. My clinical interest include: adolescent male health, gender care, mental health and access to reproductive care.
