Student and Community Instructors
Cornell Outdoor Education would not be possible without the hundreds of student instructors and community members who teach our classes and staff our facilities. Often graduates of the PE classes themselves, students receive extensive training in "hard" skills, like advanced paddling strokes and rescues, as well as the "soft" skills that are necessary to teach and lead students through their experiences. Our instructors are the heart and soul of these program and we are truly grateful for their contributions.

Lindseth Climbing Center Manager
Josh’s roundabout route to COE includes work as a graphic designer, camp counselor, woodworker, produce clerk, and customer service manager, not necessarily in that order and sometimes all at once. Although he has always loved adventuring, it wasn’t until his boss took him to the Gunks in 2003 that climbing became a focus of his energy. These days, Josh is always itching to get off the ground, but will happily give you a belay if you ask.
Land Programs Coordinator
Born and raised in Ithaca, Chris spent his summers working at camps along Cayuga Lake. After college (BA in psychology) Chris started working for the Hurricane Island Outward Bound School.

Chris accumulated over 1800 field days as an Instructor and Course Director from Florida to Maine and stops in between.
Climbing Program Coordinator
Believing that experience is the best way to learn, Andrew likes to jump in feet first. He has been backpacking since he couldn't carry a helpful load and started to experience the snow bundled in a pulk behind his parents. While studying Geological Sciences at University of Oregon, he fell in love with rock climbing and has worked in challenge course and industrial rope access settings so that he can look out on beautiful scenery with great people ever since.
