God has given pastor Chamron a unique testimony of witnessing Christ as a survivor of the Khmer Rouge killing field in the 80s. He has since escaped to the US, called to be a pastor, and has served in First Covenant Church Oakland and has led teams to go back to Cambodia to bring healing and reconciliation to different groups each year.
His ministry in Cambodia is holistic and from the ground up. His priority is to train and equip indigenous leaders. He has started more than 50 churches in Cambodia and each year he would lead a team from the US to visit these churches and partner with them in reaching out to former Khmer Rouge militants, children, and the neediest places in Cambodia that are not yet reached by the other missionaries and aid groups.
