The Fetal Institute

The Fetal Institute provides patients with the latest and most advanced resources in the field of Maternal-Fetal Medicine and Fetal Therapy. This includes high-resolution ultrasound imaging, non-invasive serum screening and prenatal testing (NIPT), as well as comprehensive invasive prenatal diagnostic and therapeutic techniques. Fundamental to the philosophy of the Institute, all diagnostic and therapeutic options are performed using either a non-invasive or a minimally invasive approach, which results in better pregnancy outcomes.

Founded by Dr. Ruben Quintero and Dr. Eftichia Kontopoulos, The Fetal Institute serves as a resource to all Obstetricians and Maternal-Fetal Medicine specialists. The Fetal Institute is a national and international referral center for the assessment and management of complicated pregnancies.
