Board of Trustees

Our Humboldt County Hospital District Board of Trustees are committed to maintaining our hospital and ensuring that its policies and initiatives are in alignment with our mission and values. Our Executive Leadership Team is led by our CEO who ensures that day-to-day operations run smoothly, efficiently, and successfully.

The hospital board includes five elected members and one appointed member.

Our board makes policy decisions and works with the CEO to ensure that those decisions are implemented in a way that aligns with the principles upon which HGH Hospital was founded.

More importantly, the board is tasked with maintaining the financial health and accountability of the hospital. This takes careful examination of our dynamic and ever-changing healthcare industry and the vigilance of engaged, insightful professionals who are committed to putting our patients first.
