Andrenna Reid, from King of Prussia, came face-to-face with the man who came to her rescue.
She began having contractions and tried to drop off her 1-year-old son at a family member's house before heading to the hospital.
But baby Santana had other plans, and Andrenna was about to deliver the baby with no roadside assistance.
That is until Robert Stenger pulled over and experienced a moment he describes as unforgettable.
"When I finally looked down and I saw a baby, like, 90% coming into the world - I've never seen it before, personally, I don't have children. It was a wild moment," Stenger said. "I remember running back to the responder, when I was getting things for you to clean up and and stuff, I was like, 'Wow!'"

Stenger was able to tell the 911 dispatchers what mile marker they were at.
State police troopers quickly arrived, along with EMTs who took the family to Jefferson Abington Hospital.
"I can't thank him enough, there's no words to describe how I truly feel. Just to see someone there just meant everything," Reid said.
Stenger says after our initial story aired, he learned Reid was looking for her.
Now, both are bonded by an unforgettable experience.
