About Us

We envision a world where every student learns about the science of nature, is inspired by its beauty, and is motivated to take action to protect the natural world.


Throughout its history, NatureBridge has benefited from extraordinary leadership. From our Board of Directors to our environmental science educators, the entire organization is comprised of leaders in their fields who are strongly committed to our mission.
