Joseph "Gabe" Sonnier used to clean up after everyone at Port Barre Elementary in Port Barre, La. Now, the former janitor is the principal at that school.
The journey to his promotion began in 1985 when Port Barre's then-principal pulled Sonnier aside, CBS Evening News reported.
"He said, 'I'd rather see you grading papers than picking them up,'" Sonnier told the station.
Sonnier had dropped out of Southern University in 1979, according to the Advocate. His mother, a housekeeper, was struggling to support his four siblings and pay for his education, so Sonnier began working to help.
But at the age of 39, while still working as a janitor at Port Barre, he decided to go back to school.
"I would come to work at like 5 in the morning and leave at 7 and go to school all day and then come back and finish up my eight hours of work here and then go home and do homework," Sonnier told KATC.
He earned his bachelor's degree, and in 2008, went from janitor to teacher at Port Barre Elementary, according to the Advocate. He later earned a master's degree in education through Arkansas State University.
