Amy Wiggins


Amy Wiggins is a teacher and sees how hunger can impact a child’s ability to learn. Amy formerly served as ECHO’s Director of Advancement. Having a passion for making a difference in the lives of children, Amy also served on the Board of Trustees for the Florida Baptist Children’s Homes for many years.

God opened her eyes to the need for ECHO’s work while serving on short-term medical mission trips with her husband Stan, who is a pediatrician, and their three sons. They would return home from their work in Guatemala and Ecuador with broken hearts, knowing that the health and nutritional needs of the children they were serving weren’t being addressed with long-term solutions. Amy considers it a joy and privilege to be supporting an organization that brings life-changing opportunities and lasting hope to families in need.

Bill Hutchison, Ph.D.

Bill has been a Professor & Extension Entomologist, Dept. of Entomology, University of Minnesota, in St. Paul, for the past 32 years. He served as Dept. Head from 2010-2015. An Arizona native, he received his BS degree (Agronomy) from the University of Arizona, and his PhD in Entomology from the University of Wisconsin-Madison. Between degrees, he spent 2 months doing ag-missions work in Honduras; this shaped his early vision for international development. With his Extension appointment, he works with growers to implement sustainable Integrated Pest Management (IPM) solutions, to reduce pesticide use yet continue to provide marketable produce. His current focus includes a rapid response to invasive pest species, the use of exclusion-netting and biological control – emphasizing high-value crops (apples, wine grapes, berry crops). During his career he has enjoyed mentoring 20+ graduate students and numerous undergraduates. Internationally, Bill has had the opportunity to work with maize IPM, with scientists in Ethiopia, Kenya, and South Africa, as well as Mexico and the UK.

Bill is an active supporter of ECHO, particularly since serving on the Board from 2010-2016. He continues to believe in ECHO’s mission, and has a passion to work with ECHO’s staff and partners, to break the poverty cycle of 800M+ who continue to be malnourished in developing countries. Enhancing the yields of staple crops, as well as increasing access to high-value fruit and vegetable crops provides additional family funding, and expands income opportunities. ECHO, in part, is like having an “International Extension Service” to smallholder farmers that has had a significant impact to date. Over the next decade, we need to do more to accelerate the movement of families out of the poverty, so that more children can break the malnutrition cycle, have access to school, and thrive.
