We hire enthusiastic science educators who love working with children in the outdoors! Each staff person must pass a background check as well as have First Aid and CPR certifications. Our youth program team is trained not only in safely managing groups in the outdoors, but in how to engage children in both fun and meaningful field science learning experiences. Staff are typically hired after already having experience as teachers and guides for youth in a variety of camps, schools or non-profit organizations.
