In 2010, Amy moved to Guatemala to become Director of EFTC, and led a team of 50 staff providing education, healthcare and social support to 600 children and families living in poverty in Jocotenango. After 4 years in Guatemala, Amy moved to Vancouver, Canada and worked in Monitoring & Evaluation for an organization developing Criminal Justice Systems in multiple countries around the world including Guatemala. 
In 2017, Amy found ODIM, and moved back to Guatemala to take on the role of  Executive Director. She is excited about taking on the new challenge of working in a rural Guatemalan community and is attempting to learn Tz'utujil.
