Dave and Debbie joined MGF in 1991. They thank the Lord for the opportunity to serve Him in Tijuana and Rosarito areas of Mexico, which are just south of the San Deigo, California border.

They have been developing relationships with many other Mixteco Indian families living at the "Sanitary Fill" in Tijuana as well as other Mexicans with whom they have shared the gospel.

The Lord has provided them with a small church building where they hold services each Sunday and Tuesday. Along with this ministry in Tijuana, they are also active in a church in Rosarito where they help and encourage Pastor Victor Mayoral. Their daughters, Cori and Michelle, are active in the youth group there.
