Michigan elementary school teacher Julia Koch was teaching her first graders remotely when one of her students started having technical difficulties.

Koch called the student's grandmother Cynthia Phillips to figure out the student's problem. That's when Koch realized something wasn't right. Koch told NBC affiliate WOOD"When she started speaking, I could tell that there was something wrong. I wasn't sure what was wrong, but there was something wrong."

That's when Koch quickly alerted school administrators, who called 911. Phillips was having a stroke. She remains hospitalized, but she is expected to survive. Phillips shared that she's already walking again, but gave a lot of praise to Koch for stepping in when she did.

The Muskegon Heights Fire Chief Chris Dean also applauded the quick thinking of Koch and her colleagues as well sharing, “I think that this teacher’s action very well could’ve saved the woman’s life, but at the least, improved the quality of the rest of her life."
