Staff Profiles

Carol Duh-Leong

Board Member, Chair

Carol Duh-Leong oversees strategic planning and operations on the organization’s board. The idea for CHIL came to Carol when she realized how challenging it was for her patients to make healthy decisions about food, health, and tobacco outside of clinic. The organization was born when she asked her friends in education, public health, and public policy what they can do together to create and improve healthy behaviors in children. Outside of CHIL, Carol is a resident physician in the Social Pediatrics program at the Children’s Hospital at Montefiore. Prior to residency, she served several years on the board of directors of Doctors for America where she had the opportunity to advocate for patients everywhere from church basements in South Carolina to the White House Rose Garden. Her writing has been published in The New York Times, The New Physician, the KevinMD blog and the Doctors for America blog. She received her MD from the Vanderbilt School of Medicine, her Master’s in Public Policy from the Woodrow Wilson School at Princeton University, and her undergraduate degree from Yale College.
