I am currently a gastroenterologist at Kaiser South San Francisco. I completed my fellowship training at UC Irvine where I was Chief Fellow and developed a passion for endoscopy, colonoscopy, inflammatory bowel disease and comprehensive digestive health.

Before my career in gastroenterology, I attended UC Berkeley for undergraduate where I received a Bachelor’s Degree in Bioengineering with high honors. I later attended the University of California San Diego and obtained a Master’s of Engineering in Bioengineering. I eventually decided to pursue a career in medicine and went to Tufts University School of Medicine for medical training. I completed my residency in Internal Medicine at Santa Clara Valley Medical Center, where I also served as Chief Resident.
