Hillcrest Elementary teachers now know exactly how to react in a medical emergency, but that was not the case two and a half years ago when their 61-year old PE teacher Harry Edmondson collapsed at school and died.
"Everybody was unprepared," said teacher Cindy Campbell, "Nobody expects anything like that to happen and so it caught everybody off guard.
Coach Edmondson's death taught them the importance of preparedness.
That's why 25 Hillcrest teachers volunteered their time to learn what to in a medical emergency.
Tammy Crowder is a nurse and first aid instructor with Parkridge Medical Center.
She taught the teachers several life saving techniques and how to work as a team.
"Should God forbid something like this happen at the school. They already have that bond with their fellow teachers who were here tonight that they know. 'she knows what to do, I'm gonna grab her,' and they can keep each other calm," Crowder said.
Teachers say that's especially comforting after seeing mass tragedies in schools and unexpected places across the country.
"That situation that happened in Boston, we all have children, we all have our students, and we think about what could happen and we just want to be the ones who are there to help them in case something every happens," said teacher Kristina Culberson.
