I am going to disagree with filmwaves and say the last name Vossos does exist. There are even famous people with that last name in Greece like Sofia Vossou. And this is the way it's spelled Βόσσος or Βόσσου and in English Vossos or Vossou, not Bossos that would translate in greek to Μπόσσος. In fact my pulmonary specialists names is Andreas Vossos. So, what info are you searching for?
