About author

Dr. Reem Saadeh-Haddad, MD, is a board-certified clinical geneticist who cares for children and families with rare genetic, metabolic, and hereditary conditions across the Washington, DC region. She earned her medical degree from Georgetown University School of Medicine in 2001, completed internship and residency training at New York University (2002 and 2004), and then pursued subspecialty fellowship training in Clinical Genetics at Johns Hopkins, finishing in 2007. Over the past two decades she has built a reputation for careful diagnosis, clear explanations, and compassionate counseling, helping patients understand complex test results and make practical decisions about surveillance, treatment, and family planning. At MedStar Georgetown University Hospital she practices pediatric clinical genetics and serves on the faculty in the Division of Pediatric Genetics & Metabolic Disorders (assistant professor), where her interests include dysmorphology, pediatric genetics, and cancer genetics. She is certified by the American Board of Medical Genetics and Genomics and maintains active hospital affiliations with MedStar Georgetown University Hospital; her clinical profile highlights broad experience in ordering and interpreting diagnostic and predictive genetic testing, including panels for inherited eye disease and hemoglobinopathies. MedStar Health Dr. Saadeh-Haddad also cares for patients at Sibley Memorial Hospital and is listed among Johns Hopkins Medicine’s pediatric genetics specialists, reflecting her longstanding collaboration with that network and her commitment to accessible regional care. Hopkins Medicine Profiles+1 In addition to hospital-based practice, she offers tele-genetics consultations through Commonwealth Clinical Genetics, extending evidence-based counseling to families who prefer virtual visits while preserving the same careful review of history, testing options, and follow-up plans. Licensed in the District of Columbia, Maryland, and Virginia, she provides continuity across state lines for complex or chronic conditions that need coordinated, multidisciplinary management. Patients and colleagues consistently note her skill in translating technical findings into plain language and her collaborative approach with primary care, oncology, neurology, cardiology, and maternal-fetal medicine teams. At Georgetown, she contributes to medical education—regularly lecturing and co-directing courses—so that future clinicians learn to think genetically, order tests judiciously, and counsel ethically. Commonwealth Clinical Genetics Website+1 Whether evaluating a newborn with multiple congenital anomalies, a child with developmental delay, or an adult with a strong family history of cancer, Dr. Saadeh-Haddad emphasizes accurate phenotyping, appropriate use of next-generation sequencing, and thoughtful discussion of variants, privacy, and implications for relatives. Her goal in every encounter is to pair cutting-edge diagnostics with practical care plans that fit each family’s values and resources, and to ensure that results—positive, negative, or uncertain—lead to actionable guidance and supportive follow-up.
