McMichael reminded his fellow graduates that "Fallston prepared them for whatever lies ahead."
"This is Mitchell McMichael, signing off," he said. "Stay tuned as our stories develop."
The graduates also heard from five local elected and appointed officials who imparted their adult wisdom.
Board of Education member Robert Frisch, state Sen. J.B. Jennings, Del. Pat McDonough, Arden McClune, director of the Harford County Department of Parks and Recreation and County Councilman Joe Woods all addressed the students.
Jennings, who also spoke at Bel Air High's graduation, told graduates they had experienced thousands of school lunches, bus rides and quizzes and tests in their years at public school students.
"You all have been given one of the greatest educations in the world," he said. "It is up to you to succeed and move forward with it."
McClune reminded the graduates "learning is a lifelong activity."
"You'll continue to grow and change all of your life," she said. "We all remain a work in progress, congratulations!"
Friends and relatives of the graduates cheered and screamed with delight as each one's name was called to receive his or her diploma.
Joe and Sandy Klima of Forest Hill cheered as they heard the name of their niece, Stephanie DiMario.
"I'm relieved that the day's finally come, and she's on to a bright future," Sandy Klima said.
Tim Ollivett was equally proud of his son, Christopher, and noted his daughter recently graduated from college.
"It's kind of exciting and sad at the same time, because they're growing up and they're going on with their own lives," he said.
A.J. Alexander of Fallston shook his son Wyatt's hand as he exited the arena and told him, "you're a man now."
Wyatt, 17, who will be attending James Madison University in the fall, said he was "kind of nervous, but at the same time anxious to see what's next, what's to come."
Alexander said he expects his son will "go far if he applies himself."
"He has to work at it," he said. "It's not going to come easy, but he's got all the tools."
Principal Richard Jester presented the Class of 2013.
"Ladies and gentlemen, I proudly present to you, a group of young men and women ready to make an impact on the future!" he announced.
