Leadership & Board of Trustees

The Natural History Museums of Los Angeles County (NHMLAC) are governed through a public-private partnership, composed of dedicated individuals serving on our Board of Trustees and the County-appointed Commission of the Board of Governors. Together, the Executive Leadership Team and the Board work to champion the museums' vision, protect the collections, and carry out their strategic goals.

Executive Leadership

The Executive Leadership Team works to advance the museums' strategic priorities—to commit to principles of accessibility and engagement, and to become a hub for discoveries and dialogue around critical issues of global significance and local impact.

The Executive Leadership Team collaborates with the Board of Trustees, various government agencies, private entities and foundations, along with over 480 NHMLAC employees, to inspire wonder, discovery, and responsibility for our natural and cultural worlds.
