I grew up hiking in the Wasatch Mountains and, after completing college in Utah, I moved to Philadelphia to attend medical school at the University of Pennsylvania in 2005. After graduating in 2009, I came to Stanford for my general internal medicine internship and residency, was invited to stay as a chief resident in 2012, and then stayed again for oncology/hematology fellowship in 2013 before joining the faculty of the division of oncology in 2016. Here at Stanford I pursue my twin passions of providing excellent clinical care and mentoring the next generation of physicians.

I specialize in the care of patients who have gastrointestinal tumors, including tumors of the pancreas, large and small bowel, liver, and biliary tree. I have experience with rare GI tumors--including both intra and extra hepatic cholangiocarcinoma--and trained under Dr. Pamela Kunz, one of the country's leading experts in the care of patients with neuroendocrine tumors and have thus seen a large number of these patients, as well.

I am lucky to have a first rate medical team by my side consisting of a nurse coordinator, a nurse practitioner, and a physician assistant. We strive together to provide capable, compassionate, responsive care and make the care of our patients our highest priority.

In addition to patient care, I am a devoted medical teacher and have worked over the past five years to elevate the teaching of medicine at Stanford University, where I have taught medical students, residents, and fellows, including conducting a randomized, controlled trial hoping to optimize the way we teach communication skills to nascent physicians.

Fluent in Spanish, I have lived in both Mexico and Argentina and am comfortable in virtually all medical situations conversing fluently in Spanish without an interpreter. I especially enjoy providing care to patients who speak Spanish as a first language.
