It was December 21st, just days before Christmas, when Scott Tedder stopped by the Heffernan house in Highlands Ranch to collect a final payment for roof work completed on Dave Heffernan’s son’s home. He wasn’t scheduled to be there that day — he arrived earlier than planned, a seemingly small decision that would end up saving a life.

As they chatted, Dave handed over the check and took a quick photo of it for records. It was the last thing he remembered before everything changed.

In an instant, Dave collapsed. Scott recognized the signs and acted fast. Within 30 seconds, they were on the phone with emergency dispatch. The operator gave instructions to Dave’s wife Katherine who was told to count aloud while Scott began chest compressions.

Years earlier, Scott had worked as a lifeguard in Highlands Ranch — training that had clearly stuck with him.

What felt like moments stretched into 12 minutes, according to paramedics. But Scott never stopped. He was relentless, calm, and focused — driven by instinct and courage.

Had he arrived at his originally planned time, Scott wouldn’t have been there. Dave might not have survived. But thanks to his quick action, Dave pulled through — with no neurological damage.

For his lifesaving training and actions Scott Tedder will receive the Lifesaving Preparedness Hero of the Year award at the American Red Cross Rocky Mountain Heroes Soirée on Saturday, May 3, 2025.  

We are deeply grateful to Brian Casey for making this award possible and for his ongoing support of the American Red Cross of Colorado and Wyoming.
