Four U. S. Postal Service carriers at the Monroeville Post Office entered elite company Wednesday.

They each have served more than 30 years without getting into a preventable crash on their routes. It’s a rare feat, accomplished by only 2.5% of all letter carriers, said Ted Lee, representative for the National Association of Letter Carriers.

“It’s having safe habits, always wearing your seat belt. We want everybody to go home the same way they came to work,” Lee said.

The four carriers were inducted Wednesday into the Million Mile Club, which is part of the Safe Driver Award program created by the National Safety Council. It recognizes carriers who have driven 1 million miles or accumulated 30 years of service without a preventable crash.

Letter carriers took a quick break Wednesday morning from preparing for their routes to honor their four colleagues with local post office leaders. Paul Devito of Forest Hills, George Getlak of Plum, John Olsen of North Huntingdon and Lisa Stumpf of Manor were presented plaques, pins and jackets for their combined 138 years of safety on the road.

Since she started in the 1990s, Stumpf said, there are more vehicles on the road and drivers have access to cellphones while behind the wheel. She attributed her clean driving record to paying attention to what other drivers are doing.

Her route consists of about 515 addresses in the Ramsey Road area and involves about two hours of walking daily with the rest behind the wheel.

“I’m happy. It’s really impressive,” she said.

It’s a difficult honor to earn, agreed Aaron Thorne, vehicle maintenance facilities manager for the Pittsburgh area, and Thomas Joyce, safety specialist.

“To do this for 30 years without having an at-fault accident, that’s pretty good,” Thorne said. “This is a major achievement.”

Safety specialist Celeste Devito said carriers on the road regularly encounter other drivers on cellphones and other hazards associated with distracted driving. She praised the four carriers and their safety records.

“You don’t see it very often, and to have four of them in one office is amazing,” she said.

One of them was her husband, a Marine veteran.

“His caring, not only in the streets and to his customers, has always manifested at home,” she said. “It’s an honor. It’s an incredible thing to be here today.”
