To see the impact one man had on the University of Denver, all you had to do was look into the crowd Wednesday afternoon. There weren't enough seats in the room.

In Davis Auditorium at Sturm Hall near the heart of DU's campus, hundreds of people gathered to celebrate the life of "Petey". Fittingly, Peter Naffah was the heart of both the DU community and the defending national champion Pioneers hockey team.

"A big part about what we talk about in our family is being selfless," DU hockey coach Jim Montgomery said. "Petey was incredibly unselfish."

"Petey" had been a volunteer equipment manager with the Pios for the past four years. Coach Montgomery brought in the man with down syndrome, and he immediately became a part of the team. More than that, he was family.

Peter tragically passed away a little over a month ago after a battle with meningitis. Wednesday, his family, the team and the entire community came together for a touching memorial service to honor his life.

The countless stories from friends and family showed just how much he meant to everyone in attendance.

"Our family will be forever grateful for our precious Pete, and the love and joy he brought to us," his mother, Kathi, said. "We will honor his bright light by remembering his priorities."

From immediate family, to friends with Adam's Camp and Special Olympics Colorado, to his girlfriend and the entire hockey team, everyone had a story about Peter they won't forget.

One of those was told by former DU hockey captain Grant Arnold, Petey's favorite player on the team.

"One day at practice, my shoulder came out, and I threw my gloves and stick on the bench and went to the locker room. I was just done," Arnold said. "Petey leaves the bench and comes into the locker room."

"He sits right next to me like he always did and puts his arm around my neck and says, 'It's going to be ok, Grant.' I looked up and saw how much he cared about me in that moment."

Coach Montgomery had a similar story.

"One time, we weren't practicing very well," Montgomery said to the packed auditorium. "I lost my temper. After my tirade, I went to the bench. Petey comes up to me--I'm guessing my face was flushed red--and says, 'Are you going to be ok, coach?'"

"And, he gave me a hug. Meanwhile the team is in tears laughing, because, what can I do? All I could do was hug him back. So, I did.He brought that levity to us that was so important to our family."

It was a day of both remembrance and healing. And, it came along with a touching promise from the head coach.

"We dedicate the rest of this season to our Petey, who made us all better people," Coach Montgomery said. "And, on April 7 (the date of the 2018 NCAA national championship game), Petey will be dancing with us again."
