Like so many of us, when not out on the trails in the Seashore, Claire is tethered to a computer. As the writer and editor at Migrant Clinicians Network, she has written extensively and widely on health equity and migrant health. Outside of MCN, Claire’s publications center on environmental and social justice, natural history, and green living. On Saturdays, Claire can be found at Martin Griffin Preserve of Audubon Canyon Ranch in Stinson Beach, where she organizes and facilitates volunteer trainings and manages the preserve’s public season which runs from May through July. In 2018, Claire’s daughter, Viola, worked with fellow third grader Reese Patton to encourage West Marin businesses to ditch plastic straws.
