    Philosophy of Care
    As a teenager, I spent many summers working at a day camp with children. Because of this, I chose a career in pediatrics to combine my interest in science with my love of children. I especially enjoy the continuity of care that pediatric medicine allows in caring for patients from infancy though adolescence, as well as the connection and friendships I share with my parents.

    Hobbies
    When I am not working with patients, I enjoy kickboxing, dancing, crafts and spending time with friends.
