Dan Rademacher, Project Director

Dan Rademacher is Stamen's Project Director. He lives by checklists and calendars, even on weekends. He’s a cofounder of Nerds for Nature, where he leads the grassroots bioblitz program. For a decade, he was the make-it-happen guy at Bay Nature Institute. Before that, he did a stint as a custom cabinetmaker and narrowly escaped getting a PhD in literary criticism from UC Berkeley. He has been known to leave his laptop and actually hike outdoors.
