About Us

Founded by landscape architect Charles Eliot in 1891, The Trustees has, for more than 125 years, been a catalyst for important ideas, endeavors, and progress in Massachusetts.

Who We Are

As a steward of distinctive and dynamic places of both historic and cultural value, The Trustees is the nation’s first and Massachusetts’ largest preservation and conservation nonprofit, and its landscapes and landmarks continue to inspire discussion, innovation, and action today as they did in the past. Supported by members, friends and donors, The Trustees’ more than 100 reservations are destinations for residents, members, and visitors alike, welcoming millions of guests annually.

What We Do

We enjoy and care for more than 100 special places—nearly 27,000 acres—all around Massachusetts. And we are actively building an extended family of friends, neighbors, and partners across the state that can help in many different ways. Each year, more than 2 million people visit our reservations, 250,000 people participate in our more than 5,000 programs and events, and volunteers contribute over 50,000 hours of assistance in all aspects of our work. The Trustees is a vibrant and growing network of people who are committed to preserving the Commonwealth’s landscapes and keeping open space open for everyone, forever.

What We Care About

For more than 125 years, The Trustees has been on the ground in communities across Massachusetts, working to protect special places, providing loving care of our reservations, building creative new programs to engage people, and sharing our expertise with neighbors and partners.
