Our Team

Delta Institute is a 501(c)(3) organization formed in 1998 that envisions a region in which all communities and landscapes thrive through an integrated approach to environmental, economic, and social challenges. Working with our partners, we identify opportunities for environmental solutions and design, test, and share solutions that yield social, environmental, and economic benefits for communities.

Delta is committed to full integration of diversity, equity, and inclusion (DEI) into all internal processes and structures for our board and staff, and external processes and structures for engaging with our partners, communities, stakeholders, and supporters.
