Personal Statement

"My clinical practice focuses on two main areas: prenatal diagnosis of fetal abnormalities and consultation in managing complicated pregnancies. Our ultrasound unit has special expertise in first-trimester ultrasound and risk assessment for fetal chromosomal abnormalities, such as Down syndrome. We also offer expert prenatal diagnosis with second-trimester ultrasound. When indicated, I perform chorionic villus sampling (CVS) and amniocentesis procedures."
