About Me

I take pride in providing compassionate guidance for patients that are bravely navigating serious illnesses. Hospitalization ranks among the most challenging moments of an individual’s life, and I aim to empower patients by blending their unique values with expert medical care.

As an academic hospitalist at University of Vermont Medical Center and Assistant Professor at University of Vermont Larner College of Medicine, I am proud to serve as an educator for patients and future physicians.

Outside of work I enjoy fishing, bird watching and cooking for friends and family

I aim to empower patients by blending their unique values with expert medical care.
