Our physicians are obstetricians who have received additional training in the subspecialty of maternal-fetal medicine. We have experience and expertise in prenatal diagnosis of congenital abnormalities, care for women with multiple gestations (twins, triplets or more), care for women with obstetric complications of past pregnancies or their current pregnancies — with health issues ranging from asthma to diabetes to heart disease — and care for women carrying babies with birth defects.
