Shilpa P. Chetty


  • Assistant Professor, Ob/Gyn, Reproductive Sciences
  • Perinatologist and Medical Geneticist


Dr. Shilpa P. Chetty is an obstetrician and gynecologist who specializes in high-risk pregnancy and perinatal genetics. She is the Interim Perinatal Director for the Fetal Treatment Center. She has a special interest in prenatal diagnosis, fetal anomalies and the management of pregnancy complicated by medical and genetic disorders.

Chetty completed a medical degree at Loma Linda University, School of Medicine, followed by an internship and residency in obstetrics and gynecology at Washington Hospital Center in Washington, D.C. Subsequently, she completed a fellowship in Clinical Genetics at the National Institutes of Health in Bethesda, Maryland, followed by an additional fellowship in maternal-fetal medicine at Stanford University. She is board certified in both obstetrics and gynecology and medical genetics.
