Alexandra Sims MSSPAlexandra Sims, MD

Dr. Alexandra Sims originally hails from Richmond, VA. 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. While there, Dr. Sims 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, Dr. Sims 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 completed her Pediatrics Residency at Children's National Health System in Washington, D.C., in the Community Health Track, served as Chief Resident for the 2016-2017 academic year, and will be a Children’s National General Academic Pediatrics Fellow 2017-2020. Her academic interests are in adolescent health, education and learning, juvenile justice and social determinants of health.
