Sean  Gillingham Family Practice team member

Sean Hunsberger

Originally from interior Alaska, I have lived in Portland for the past 3 years and joined Todd Gillingham MD, LLC in 2021. With a background in inpatient care, I enjoy continuing to learn and grow my medical skills. I enjoy working at Gillingham’s family practice because it allows me to connect with people and getting to know the patients. Outside of work, I enjoy a various number of activities such as hockey, playing video games, and going on small weekend road trips if possible.
