Volunteer of the Month


Trail Patrol, Land Steward

Tim has always been an avid hiker looking for the best places to explore around Santa Clara County. When he read about Coyote Valley Open Space Preserve in a local paper he decided to check it out and it soon became regular favorite. He spotted an ask for volunteers to go out to help build a fence at Coyote Valley; he attended and loved working with fellow Authority volunteers and staff. He has since become an involved member of our volunteer community. Between his shifts working as a firefighter with NASA, watching for fires at the lookout station with CAL FIRE and his commitments as a student for a citizen's academy for Valley Water, Tim has been a regular volunteer for both Land Stewards and Trail Patrols. Anyone who has met Tim appreciates his warmth, professionalism and wonderful sense of humor. Thank you Tim for all your excellent service!
