Mentor / Naturalist

We belong outside, and GRP Mentors take us there.

As a Mentor, you will join a small cohort of experienced educators who are dedicated to learning, exploring, and sharing knowledge about the natural world. They come from many fields, and from many stages in life. What they all share is a passion for working with children and young adults.

Almost every day, you will lead up to 12 campers on a leisurely hike to one of Green River Preserve’s coveted destinations. We value your teaching skills most of all, and we’ll train you to lead hikes to our cave, to swim in the headwaters of the Green River, to climb to the highest peak on our property, to take a polar plunge under Uncle’s Falls, and more. We hire Mentors for our full summer season and our fall and spring school programs.

Supported by a strong team of directors and peers, Mentors are leaders in our community.

Each Mentor will adopt a set of campers and cabin staff. You won’t live with them, but you will build strong relationships. Mentors support our Counselors as they learn and grow through a challenging summer job.

For example, Mentors support their counselors during the planning process of the Counselor-led backpacking trip, and then spend one of the two nights in the field. By providing limited guidance and then pushing Counselors to be independent, Mentors help them grow into their role as educators, trip leaders, and thoughtful people.

Mentors are the heart of Green River Preserve.

As a GRP Mentor, the peak of your teaching experience will take place at the end of our two- and three-week sessions.

You will lead one to three all-day programs that you design or co-design. We call these Group Learning Projects. Ranging from archery intensives to epic hikes, from crafts and music to lazy reading days, GLPs offer a chance for Mentors to get creative and flex their teaching muscles. (As part of your application process, we will ask that you submit a lesson plan for one of these after your interview.)

Mentors have an honored place in our community.

For their kind attention, star-power, and knowledge, campers love and admire them. For their humor, support, and wisdom, Counselors revere and respect them. Thanks to their leadership and passion for connecting children to nature, our Mentors make GRP a rich and hopeful place to work.
