Trinity has a rich history of youth mission work trips. In 1992, Dave Gaulke and Dalene Davies led the first group of six youth to work camp in Tennessee. Maurice and Betty Dyer, who became high school youth leaders the next year, took eight youth to Ohio in the summer of 1993. Over the years, the mission groups grew to include greater numbers of youth participating. By Maurice and Betty's last year as leaders in the summer of 2002, 46 youth and 13 adults traveled to Pennsylvania for Betty and Maurice's final work trip.


In 2003, Jack and Amy Bishop became the new high school youth leaders . They continue to help our youth realize their mission commitment and have lead groups to and Minnesota, Wisconsin and Kentucky.

In February 2008, a six-member delegation visited Casa de Zinc. Delegation members were Dave Endriss, Denise Core, Betty Dyer, Blair Lawson, Larry Lepper and Mary MacKenzie.The delegation visited 13 of the 14 homes in the settlement (the remaining family was at the hospital waiting the arrival of a new baby).

The delegation delivered garden tools, seeds, aprons (sewn by Trinity members), children's books, crayons, tablets and fruit roll-ups to each family. The gifts were purchased with donations from Trinity members and friends. The delegation visited additional cantons to see projects completed with the assistance of several other central Iowa churches and their sister cantons. Other special highlights were spending the week with Kathy Mahler, mission co-worker and the Pastoral Team, pictured at right, and seeing the water filter production and the Don Justo coffee finca.
