Board of Directors

Jerry Zimpelmann


Board Chairman

Jerry Zimpelmann and his wife, Lynn, reside in Eagle River, WI, where Jerry owned and operated a construction company. The company was sold in 2002 and that afforded Jerry, at age 52, the opportunity to get involved in work and projects to help further the Kingdom and build bridges to the Gospel. Since then he has been involved with the directing relief and rebuilding efforts in New Orleans after Katrina, building a school and church on the island of Grenada and recently was sent in to begin organizing the relief effort in Puerto Rico. Jerry also serves on the Governing Board of Wisconsin Lutheran Seminary.

In 2007, Jerry and Lynn purchased a piece of beachfront property in the newly discovered Costa Maya area of Mexico. In the course of things that the LORD miraculously directed, Costa Maya Ministries came to pass (you can read more about that on the history tab of this website).

Jerry is a nearly lifelong member of Christ Lutheran in Eagle River where he has served in many capacities over the years. He and Lynn have been blessed with 5 children and 13 grandchildren, all of whom are children of Jesus, all of whom are children of their Lord.
