Finally, someone who wants to show the world that occassionally first responders are heroes, but most days, we are just ordinary people like everyone else.”

“As first responders, we are highly trained to help others, to fix emergencies, and to stay strong in the face of crisis. But that same training can make it difficult to recognize when we need to help ourselves—when the weight of the job and years of trauma begin to take a toll. Cover My Six is the resource we’ve been missing. This book is a must-read for every firefighter and paramedic!”
