If you don't mind travelling into Chania, Maria Christoforatou
is an excellent English speaking private GP. If you want something closer there is a health centre in Vamos
and, although I have never used it, I think many staff speak English. If he is the same Dimitris Gogas
that used to be a pathologos in the IKA building on the Souda road he is now in Georgioupoli and speaks English. If you need something more extensive then Gavrilakis
is a fully equipped private hospital where virtually everybody speaks English.
No, 999 is NOT the emergency number in Greece. See Greek emergency numbers here
