Tim grew up in Eritrea, Ethiopia, and Liberia. His academic training is in horticulture, pursued with a desire to serve small-scale farmers in resource-constrained settings internationally. To that end, he spent two years as an agriculturalist in Ethiopia prior to joining ECHO in 2003. ECHO is an organization that seeks to reduce hunger by equipping people with agricultural resources and skills. Tim leads a department focused on distilling and sharing information gleaned from farmers or those working with farmers, research trials, and scientific literature. Tim’s team also responds to inquiries from ECHO’s global network and maintains a library of materials pertaining to tropical agriculture.
Tim is married with two boys. His yard features fruit trees and other plants grown at ECHO. He enjoys keeping fresh and saltwater aquariums, with a particular interest in growing coral.
