The Mexico Medical Mission is the by-product of the 1989 relief effort to help earthquake victims of Mexico City. This work was overseen  by the elders of the Bridge Avenue congregation in Weslaco, Texas. Upon completing that relief work, the contributing congregations requested that the remaining funds be used for evangelistic and humanitarian work in Mexico. 

Research to determine the greatest need was conducted through meetings with both Mexican and U.S. church evangelists and leaders. It was decided that “free” medical and dental health services were desperately needed in remote villages or poor sections of Mexico where these services were not available or where people were too poor to afford them. Medical campaigns were scheduled at or near local churches that provided the support services needed. Local preachers and congregations are still very active in the campaigns today. 

Today this work continues with the help of many U.S. congregations and their team members.
