Galis is married to Eleni Panagiotou, and he has one daughter, named Stella. Since his official retirement from playing professional club basketball on September 29, 1995, and up until early 2006, Galis was the owner of a summer basketball camp in Chalkidiki, Greece. The basketball camp was listed at the Athens Stock Exchange. As a token of appreciation for his contribution to Greek sport, Galis was chosen to be the first torch bearer, in the final round of the Olympic Flame, for the Athens 2004 Summer Olympics. Galis entered the stadium at the conclusion of the Opening Ceremony, and set off the procession of the flame to the altar.
