About Me

Dr. Jonathan Weiss has provided perinatal care in the East Bay for over three decades. Dr. Weiss developed the prenatal diagnosis center at East Bay Perinatal and then at UCSF Benioff Children's Physicians to provide cutting edge technology to patients throughout the East Bay. His focus is helping patients during a difficult time in their lives coping with a high-risk pregnancy.

Dr. Jonathan Weiss serves as the director of UBCP Maternal-Fetal Medicine’s prenatal diagnosis program. In this role, Dr Weiss oversees a group of critical diagnostic procedures used to assess fetal well-being. Under Dr. Weiss’ leadership, a highly experienced staff provides genetic counseling, first & second trimester ultrasound (including ultrasound for fetal nuchal translucency), amniocentesis, and chorionic villus sampling (CVS) services. Dr. Weiss brings a highly intuitive understanding of the ever-increasing role technology plays in modern maternal-fetal medicine. (Spanish speaking)
