Dr. Jenny Daci Yang (also known as Kuang Daci) was born in China and grew up in Brazil. She received her medical degree from the University of Sao Paulo in Brazil. She completed her Internal Medicine residency at Baylor College of Medicine in Houston, Texas; as well as her Gastroenterology fellowship.

I strive to provide compassionate, high quality and evidence-based care to every patient while remaining conscientious of each patient’s individual preferences and needs.
