Natalie's Everyday Heroes: Substitute teacher Pam Oehldrich 

MILWAUKEE (CBS 58) -- Pam Oehldrich may be retired, but you'd never know it. She travels, kickboxes, and still works. 

She's a substitute teacher at Urban Middle School in Sheboygan. And she's back in the classroom, teaching an important lesson in giving back. 

"I put my name on the board," she announced to a class of 6th graders.

Oehldrich calls herself Mrs. O. 

"Instead of my long last name, that works out pretty good," she told the students.

But those who know her call her something else. 

"She's like our angel here on earth," said Michelle Perronne, who's known Mrs. O. for 46 years, first as a teacher and now as a coworker.  

Maybe she's the Queen of Hearts.

She's brought her passion to the classroom at Urban Middle School for decades.

"This is a fun game you guys," she told her new group of students, teaching them different card games.

After retiring in 2004, she started working as a substitute teacher. 

This class is helping kids learn card games as part of a bigger project. 

"And eventually, they're going to make their own games up," Oehldrich said.

She deals out patience and dedication, of course. But Mrs. O. is so much more. 

"She always seems to put everybody else first instead of herself," Perronne said.

Oehldrich could have stayed retired. 

"Well, my husband passed away. And I didn't want to sit around. I wanted to make sure I was still busy and doing good things for people," she said.

Her job now isn't just helping students. Oehldrich gives away all the money she makes. 

She makes donations to the Sheboygan Fire Department.

"From donating a grill to the firefighters, providing lunches, she's always been a very big supporter of our department," said Chase Longmiller, battalion chief at the Sheboygan Fire Department.

And the Sheboygan Police K-9 unit. 

"I think she's the longest-running single person donor that we have," said Joel Kuszynski, a captain with the Sheboygan Police Department.

"Everybody needs a Pam," Perronne said.

She said Oehldrich's generosity is endless.  

"Really. She's just that kind of a person that is genuinely, genuinely nice and caring," Perronne said.

And she has no plans to fold anytime soon. 

"I mean, I'll just keep going until probably God says, hey, your time is up, you've gotta relax now. But otherwise, I'll continue for as long as I can," Oehldrich said with a smile.

Mrs. O. is also very involved with the Lions Club and the Salvation Army. She said she learned this lesson of giving back from her parents. She wants to be the reason someone smiles every day.
