Once on site, a workshop, led by the country manager, is done to discover the unique characteristics of each team, and the unique skills of each team member to match the village needs. There always are options for work projects. In Pommern, where Global Volunteers has worked for over 20 years, and I have been 3 times, the team members have a choice of teaching English, doing light building and maintenance work, or working in health care.
Since there's no dentist for over 20 miles from the village, I've been using my skills to set up a dental facility. Some patients I see have had toothaches for as long as 6 years, and they walk or bike over 4 hours to be seen. The dental facility is currently able to extract, clean, and teach preventive oral hygiene. I am returning two more times this year so that basic fillings can also be done. There are over 1,300 students in the primary and secondary schools who are being taught proper preventive oral hygiene. Each one is given a toothbrush and toothpaste. They're also taught to use salt water once the toothpaste is gone. I'll return in August with restorative materials and will be then be able to do basic fillings along with the oral surgery, oral hygiene, and preventive care. And, a very nice dentist in Iringa has agreed to do root canals and restorations so people don't have to walk around with teeth missing.
So the bottom line is, to name the three most important issues in the world. These can be either local or global. And use that as a starting point, and do something about it. This I know: Any skill a team member brings is always appreciated and used around the world. Volunteering with Global Volunteers is a wonderful experience one never forgets (and doesn't stop doing!).
