Perinatologists

A perinatologist is an obstetrician who has special training in managing patients with high-risk pregnancies, or complications during pregnancy. As a member of the Fetal Treatment Center team, the perinatologist is responsible for managing all aspects of your prenatal care.

For further information regarding Perinatology please refer to the Department of OB/GYN website.

Our physicians will speak with you at length about your fetus’s condition, the procedure, risks, possible benefits, and possible complications of fetal surgery. They will perform your surgery and manage your postoperative care together with other members of our fetal therapy team.
