Saget originally intended to become a doctor, but his Honors English teacher, Elaine Zimmerman, saw his creative potential and urged him to seek a career in films.
Saget lived in California before moving back to Philadelphia and graduating from Abington Senior High School in 1975. His father, Benjamin (Aug– January 30, 2007), was a supermarket executive, and his mother, Rosalyn 'Dolly' (Febru– February 15, 2014), was a hospital administrator.
Saget was born in Philadelphia to a Jewish family.
