I grew up in southern Maine and attended Harvard University for my undergraduate education. While at Tufts University School of Medicine and Mount Auburn Hospital in Cambridge, my focus was on primary care medicine. I believe in the dignity of each of my patients. Respect, compassion, and reliability are among my goals in patient care. In my free time, I enjoy the outdoors and the arts, usually in the company of my family. 

My aim is to empower patients with shared, informed decision-making.

I feel grateful to work in medicine every day, and to develop relationships with my patients that empower them to feel informed and comfortable with their treatment plans. I particularly value the importance of taking time to discuss goals of care with my patients. Outside of work, I am an avid reader, and my hobbies include writing, jogging, and spending time with my significant other and out cat, Soot
