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 Chorion Villus Sampling (CVS) and amniocentesis.


Because many complications of pregnancy can be avoided or minimized by steps taken prior to pregnancy, I am also available for preconception counseling.
