Dr. Mary E. Norton is a perinatologist and clinical geneticist who cares for pregnant patients who have a fetus with a birth defect or genetic disorder or are at risk for such a condition. She performs obstetric ultrasounds, counsels patients with abnormal ultrasounds and performs prenatal tests like amniocentesis and chorionic villus sampling. She also interprets complex genetic tests, especially when abnormalities are found. Norton's areas of interest in research include applying new genetic tests to prenatal diagnosis and fetal disease, as well as patient decision-making around genetic testing and obstetrical ultrasound. She is co-director of the Center for Maternal-Fetal Precision Medicine at UCSF, as well as the David E. Thorburn, M.D. and Kate McKee Thorburn Endowed Chair in Perinatal Medicine and Genetics at UCSF. Norton earned her medical degree at the University of Washington.

Dr. Teresa N. Sparks is an obstetrician who specializes in maternal-fetal medicine, managing the health concerns of both mother and fetus through all stages of pregnancy. She cares for women with high-risk pregnancies and those who are considering a high-risk pregnancy. She also specializes in clinical genetics, addressing genetic conditions that affect a woman or baby during pregnancy. Sparks' research investigates the causes of nonimmune hydrops fetalis, a complication of pregnancy that occurs when excessive fluid accumulates in the fetus. Her work focuses on identifying the condition's genetic causes, with the goal of developing more targeted approaches to care both before and after birth. Sparks earned her medical degree at UCSF. She completed a residency through the obstetrics and gynecology program of Brigham and Women's Hospital and Massachusetts General Hospital. She then completed a combined fellowship in maternal-fetal medicine and clinical genetics at UCSF. Sparks is a member of the American College of Obstetricians and Gynecologists, Society for Maternal-Fetal Medicine, American College of Medical Genetics and Genomics, and American Medical Association. Dr. Sparks is highly rated in 12 conditions, according to our data. Her top areas of expertise are Fetal Edema, Hydrops Fetalis, Hemolytic Disease of the Newborn, and Alpha Thalassemia.
