"I don't normally wear a tie," he said before the ceremony. "But for Mr. Perry, I'll wear a tie."
Sandra Gallagher-Mohler, a behavior interventionist and member of the school's Class of 1999, presented Perry with several gifts paid for by a pool taken up by the school's faculty and staff.
Perry, a Baltimore Ravens fan, received a Ravens hat, $50 gift card and two tickets to three home games for the upcoming season in section 513.
"I've been there once, but I think it's going to be pretty exciting," Perry said of the games at M&T Bank Stadium, adding he doesn't know who he will bring with him.
He will also receive a personalized jersey with "Mr. Perry" on the back, which did not get delivered in time for the ceremony.
The school's PTSA presented Perry with a gift card to Taneytown Deli on Mellor Road, where he orders tuna on white bread with honey barbecue potato chips and a slice of pie each day.
During the ceremony, Perry received citations commending his service from Baltimore County Executive Kevin Kamenetz, Councilman Tom Quirk, state Sen. Ed Kasemeyer, and Dels. Steve DeBoy and James Malone.
Perry who said he and his wife have helped raise their nieces and nephews, is unsure how much longer he will continue in his position.
But when he does retire, he said he will miss the people at the school where he has walked the halls and stairways for so many years.
"It's been good working here. I ain't have no problem with nobody," Perry said.
