Aisha Barber, MD

Dr. Barber is originally from New Jersey and attended college at Rutgers University.  There she participated in Access-Med Phase I, a program which immersed her in the sciences, exposed her to healthcare careers, and cultivated her love of teaching through teaching assistant and tutor positions.  She was accepted into Access Med Phase II, a medical school pre-matriculation program for students from minorities underrepresented in medicine.  She completed medical school at UMDNJ – Robert Wood Johnson Medical School.  She was exposed to academic careers through a pipeline program during her senior year of medical school which changed her career trajectory.  Dr. Barber completed pediatric residency at the Children’s Hospital of Philadelphia then joined the Hospitalist Division at Children’s National Health System in 2006.  To further her effectiveness as an educator, she completed the Educational Scholars Program through the Academic Pediatric Association and the Master Teacher Leadership Development Program at George Washington University.  At Children’s National her primary roles are as pediatric hospitalist and medical educator.

Alexandra Sims MSSPAlexandra Sims, MD
Resident Co-Director

Dr. Alexandra Sims originally hails from Richmond, Virginia. She attended George Mason University, and pursued a bachelor's degree in anthropology while simultaneously completing the prerequisites for medical school. This combination of curricula at George Mason fostered a passion for medical anthropology and the intersection of health, disease and culture. Her passion for serving marginalized groups manifested in HIV/AIDS outreach both domestically and abroad in Durban, South Africa and San José, Costa Rica, as well as several other community based programs and coalition building initiatives. She participated in the BWH STARS Program at Brigham and Women’s Hospital in Boston, MA prior to medical school, and there developed a passion for workforce diversity in academic medicine. She started her medical career at The George Washington University School of Medicine and Health Sciences, where her interests in patient advocacy and underserved populations were supplemented in the Community/Urban Health Track. While at GW, Alexandra served as Chapter President of GW's Student National Medical Association (SNMA), and worked on the regional executive board thereafter. Upon graduation in May 2013, she was recognized by the Gold Humanism Honor Society, as well as the Department of Pediatrics. Dr. Sims is currently a third year pediatrics resident at Children's National Health System in Washington, DC in the Community Health Track, and will be Chief Resident for the 2016-2017 academic year. Her academic interests are in adolescent health, reproductive health, education and learning, and juvenile justice.
