Volunteer of the Month

Ted Stoll

Trail Patrol

Ted is a retired judicial staff attorney from the California appellate courts. He is a former amateur bicycle racer, both road and off-road. He loves Portuguese, Spanish, and French literature and translates them to English. Ted translated a Brazilian novel, Land of Black Clay. His favorite preserves are Rancho Cañada del Oro and Sierra Vista for different reasons. To Ted, Rancho is intimate and soothing, while posing a physical challenge for mountain bikers and offers a lovely array of wildflowers in spring. Where as Sierra Vista offers him an open and majestic setting with spectacular views of Santa Clara Valley and lots of opportunities to see eagles, red-tailed hawks, and yellow-billed magpies.
