Volunteer of the Month

Christi Cerna

Land Stewards, Trail Patrol, Special Events

In addition to volunteering with the Authority (which is one of my favorite activities), I enjoy hiking, trail running, backpacking, climbing peaks, bicycling, and swimming in creeks where the fish nibble my toes! Love, love, love being outdoors and enjoying nature! Another fun fact: years ago, I worked as an instructor when the current Open Space Authhority building was a yoga and pilates studio.
