Maternal Fetal Medicine (High-risk Pregnancies)

Maternal-Fetal Medicine

Maternal-Fetal Medicine, or Perinatology, refers to the specialized care of pregnant women and their fetuses. Our perinatologists are experienced in a wide variety of complex maternal-fetal conditions and will partner with you to keep both you and your baby healthy.

It is our goal as Maternal-Fetal Medicine specialists to care for normal pregnancies as well as those who are high-risk. Our doctors monitor and evaluate women throughout their pregnancies and deliver them at the Johns Hopkins Hospital. Learn more about our Birthing Center.
