Jeff and Pilar work at Grace International School supporting the advancement of God's kingdom in Thailand, Asia, and around the world. This ministry serves around 540 students from 344 missionary families from 20 nations working in 24 countries to reach millions for Christ. 

Pilar supports the children and families of special needs children through education. This allows missionary families to remain on the field and continue the ministry that God has called them to do.

In addition to this work, the CMF Thailand team also has ministries that reach out to children who have been victims of human trafficking and children with disabilities. Their goal is to see individual lives transformed by Christ and communities impacted by the Church.

Jeff and Pilar Prus have served with CMF for more than 20 years and have spent most of that time in Chiang Mai, Thailand, in a variety of ministries. They are the parents of twin sons: Caleb and Dillon (1998).
