John has led Rotary missions to Mexico, Haiti, Guatemala, Samoa, Vietnam and Nicaragua. He also takes a mission team from St Mark Lutheran once a year into the Río San Juan region of Nicaragua for eye exams and Bible distribution, in addition to the three Linkenheimer staffed missions.Between leading Rotary, Linkenheimer and St Mark missions to Nicaragua he has personally examined over 20,000 villagers for cataracts, pterigiums and vision prescription needs.

John and other Rotarians have made many trips to move this project along. Once completed it will be the closest source for advanced diagnostics and surgery for the 30,000 people of this remote region.
