About Our Practice

Main Line Perinatal Associates (MLPA) is a group of Maternal-Fetal Medicine specialists (obstetricians who focus on "high-risk" pregnancies) as well as a Perinatal Geneticist.

We provide pregnancy care to our own patients, usually with some complicating factor to their pregnancy. We evaluate these high-risk patients, develop a management plan, and deliver their babies.
