ecoTHRIVE Housing Board of Directors
Denise Henrikson
ecoTHRIVE co-founder and Managing Director

An artist by training with a background in public policy, Denise brings together creative practice, civic engagement, and systems thinking. For over a decade, she has used public art, deep listening, and collaborative design to explore what people need to thrive—and to translate those insights into practical policy pathways and community-rooted projects that unleash human creativity and compassion. Her experience in celebration art—lantern festivals, banners, and large-scale community rituals—shapes her belief that collective joy and belonging are essential civic infrastructure. That perspective informs her work with local governments on zoning reform, land-use approvals, finance, and cross-sector collaboration. Denise believes housing is cultural infrastructure, and that designing with care, climate awareness, and shared stewardship can help communities thrive in a changing world.

David Sloan Wilson
Human evolutionary biologist

David Sloan Wilson is an evolutionary biologist, author, and public intellectual whose work has helped transform how evolution is understood and applied. When he began his career in the 1970s, evolutionary theory was largely framed around genetic competition and self-interest, with little room for purpose, cooperation, or cultural change. Over the decades, David has been a leading voice in expanding evolution beyond biology to include cultural and social systems—understood as processes shaped by variation, selection, and replication. This broader lens helps explain how cooperation, shared purpose, and “the evolution of goodness” can emerge and be sustained, especially in human communities. Through his writing, teaching, and public engagement, David has made evolutionary science accessible to a wide audience and relevant to real-world challenges. He is a co-founder and president of ProSocial World, a nonprofit dedicated to helping groups consciously evolve toward greater cooperation, wellbeing, and collective impact. His work invites individuals and communities alike to imagine—and intentionally bring into being—a world that works for all.
