If you went to school in Sioux Falls, or still do, there's a good chance you've had a member of the Greeno or Murren families as a teacher. It's a profession that spans three generations and hundreds of years.
A 208-page book looks back on the Greeno family brothers' long teaching history.
"My first teaching position I was teaching biology, sociology and economics. History, American Government and coaching three sports; along with that driver's education," Rich Greeno said.
But plenty more chapters would be needed to show how deep the family's passion really goes. Rich Greeno is well known in Sioux Falls as a teacher and coach. So is much of his family including his daughter and granddaughter.
"When you look around, there are a lot of educators in our family," Luann Murren said.
22 to be exact. Greeno's daughter, Luann Murren, has been at the front of the class for 32 years. She not only fell in love with teaching, but someone with the same passion.
"In that family, it certainly runs deep. In my family, I just wanted a college degree and I wanted to be a coach," Marc Murren said.
Marc and Luann Murren also passed the career on to their daughter, a third-generation teacher.
"Being around all those teachers, being in the school atmosphere, I just couldn't imagine a desk job," Amy Heinert said.
Amy Heinert grew up on the sidelines of her dad and grandpa's sporting events, and in the classroom with her mom, a role now reversed.
"My childhood was spent helping mom get ready for open house, like she's been helping me get ready this week," Heinert said.
As she prepares her classroom, Heinert has the same inspiration and goals as her parents and grandfather before her.
"Teaching has changed because teaching expectations have changed. Kids haven't changed; kids are kids," Murren said.
And it's those kids who keep this family in the classroom and hopefully will add more chapters to a teaching legacy.
"It's a lot to live up to, but it's a good challenge," Heinert said.
Marc Murren is a teacher and coach at Washington High School, Luann teaches in Canton, Heinert is at Harvey Dunn and at the age of 84, Greeno still volunteer coaches at USF.
