Committed to Excellence
In 1997, former Grand Teton Superintendent Jack Neckels, along with now Emeritus Board Member Jerry Halpin, gathered a small group of people together to share an interesting idea—that Grand Teton National Park should have a visitor center that rivals its natural magnificence. With vision and purpose, the group that became our founding board of directors set out to raise funds for a state-of-the-art visitor center that would provide a way for visitors to learn about the park and explore its features in an exciting, accessible way. The project was a success, and paved the way for the Foundation to leverage those founding ideals into much more for Grand Teton today. With expert guidance from our advisory boards and generous contributions from supporters and partners, we gift millions of dollars to the park each year.
