The mission covers Greece, Cyprus, Turkey, Jordan, Syria, Lebanon, and Egypt. However, so far, single missionary elders and sisters serve only in Greece and Cyprus.
The address of the mission home is:
Greece Athens Mission Panayias Eleftherotrias 9 Kifissia 145 63 Athens Greece |
or |
Ελληνική Ιεραποστολή Αθηνών Παναγίας Ελευθερώτριας 9 Κηφισιά Τ.Κ. 145 63 Αθήνα Ελλάδα |
There is a Greece Athens Mission home page on the Web; its address is http://greece.athens.mission.net. It is maintained by David Hammond, a former missionary in that mission; you can contact him about the mission web site here.
I also encourage you to have a look at the entire Mission.Net site, a site all about LDS missions. You may also be interested in their suggested list of things to bring on a mission.
And, of course, there's the official Church world-wide Web site as well as the official LDS site in Greek for Greece.
