Computer Labs in Schools Abroad

I was on the board of Technology Services Corps (sadly, disbanded 2019). We have high school students refurbish donated computers, then take them to needy countries.

I've led trips to:

Costa Rica 2012. One school in Esquipulas, near Aguas Zarcas, San Carlos (Alajuela); second in la Union de Venecia (San Carlos).

Ecuador 2009. Two schools in and near the great market town of Otavalo.

Guatemala 2007. Estanzuela, the cleanest town in Guatemala (With Global Technology Academy, the predecessor to TSC).

An important part of this program is the effect on the students participating. We rely on student leadership. Students are from Garfield high school, which has a mixed population, and these trips are a great way to promote interaction and friendships among races in a positive context.
