Who We Are

The Open Space Institute is a team of project leaders, researchers, land stewards, attorneys, accountants and office managers--all dedicated and creative professionals united in improving people’s lives and the world we live in through smart land conservation. 

Working together over the past 40 years, we have saved 2,213,283 acres of land through direct acquisition, grants and loans. But these statistics only tell part of the story. We prefer to describe our successes in terms of the impact we have.

Our work has led to clean drinking water for millions; new and better parks for outdoor recreation; land that will endure in a changing climate; protected farms for greater access to local food; scores of local, active grass-root environmental groups; and preserved historic landscapes and vital habitats up and down the eastern seaboard.

At OSI, we get conservation done for good and forever.
