PHILADELPHIA (CBS) — Michael Nutter gave his final public speech as Mayor of Philadelphia on Monday at his alma mater, St. Joseph’s Prep.

On this first day of classes in the New Year for students at St. Joe’s Prep, Nutter spent some of the final moments as Mayor of the city. It was the same school where he spoke soon after his inauguration in 2008. Speaking in front of the student body, he praised their shared education and experience, and had a message for students.

“Do not bury your talents,” Nutter said. “Share them with the world.”

With Philadelphia’s new mayor, Jim Kenney, a fellow alumnus, Nutter said history is being made.

“For at least 12 years and probably 16, this city will be led by a Jesuit trained St. Joseph’s Preparatory High School graduate,” he told the crowd.

And with many words dedicated to the value of his past at the Prep, Nutter had a nod to his future.

“I still have more to give,” he said. “Thank you.”
