Family Medicine
For the Eel River Valley

Our Mission
The Japanese have a word, "ikigai" (生き甲斐, pronounced [E-key-guy]), to describe a person's "reason for being." A person finds ikigai at the center of what they are good at, what the world needs, what they can be paid for, and what they love. Our mission is to create a sustainable culture of support for physicians within the full scope of their work for the community.
Our Vision
We will improve health care in Humboldt County by addressing community needs, providing continuity of care across various healthcare settings and allowing physicians to thrive and flourish within their chosen scope of practice.
