Wendy Ke

I’ve always preferred being outdoors to indoors, where I feel most at “OM.” Connecting with nature is an essential part of my day that inspires and rejuvenates me and creates balance in my life. As a result, I’ve sought work and volunteer paths related to the natural environment including: working for local governments overseeing municipal environmental programs; guiding public and school naturalist programs as a National Park Service Ranger; leading active travel vacations internationally for Backroads; and volunteering in my daughter’s schools with hands on, science based programs/activities. During the time I devote to NLC’s experiential learning programs, I hope to instill in others a passion, curiosity, respect and appreciation for the natural world, as well as a desire to preserve and protect it.
