Expedition Leaders

Heading up each program is a team of talented and dynamic Expedition Leaders who have extensive experience in the field—and love working with students.

With no more than nine students to every leader, our trips give you the freedom to break into small teams and explore your interests. Meet a few of our Expedition Leaders below.
