Stony Brook Maternal-Fetal Medicine provides unparalleled care and compassion for women with high-risk pregnancies. We specialize in caring for women with preexistent medical disorders and obstetrical or fetal complications. Maternal-Fetal Medicine at Stony Brook provides care for women who are pregnant with twins, or higher order of multiples, as well as those with a history of pregnancy loss or other problems during pregnancy.

Stony Brook Maternal-Fetal Medicine understands the fetus as a patient and provides a multidisciplinary approach to the management of complicated maternal and fetal conditions. Obstetric Anesthesiologists are available “around the clock” in the labor and delivery unit at Stony Brook. Neonatologists, Pediatric Cardiology, Pediatric Surgery, and a host of other medical specialists work together to care for mother and baby at Stony Brook.
