Chrysa, a native of Serres, Greece teaches Greek at the LHI Refugee Center. And she does it all as a volunteer! Not only are her classes engaging and effective, lots of children take every second that Chrysa is on site to practice their Greek that they've learned in school.
Refugees spend a lot more time in Greece than they anticipate, as resettlement is a long process. Refugees can't work in Greece, but they do interact quite a bit with locals at market, hospital, grocery store, etc.
