Garren is a special education teacher for 3rd to 6th grade students, and on Wednesday, she was treated like the most valuable player.
From a personalized jersey to a celebration with 800 of her students, Garren even saw her favorite mascot, the Phillie Phanatic.
Every day her students high-five a hand-drawn poster of the Phanatic as they enter the classroom.
During Wednesday's celebration, they carried out that tradition in person.
"I am completely overwhelmed with the most joy. I in my wildest dreams couldn't imagine this would happen, especially someone like me," said Garren. "I love every single day. That in itself is a reward. So to have this on top of it, it's Teacher Appreciation Week."
Wednesday's celebration was in advance of Teacher Appreciation Night at Citizens Bank Park.
Garren will join nine other local All-Star teachers this Friday night at the Phillies game against the New York Mets.
