Testimonials
With Dr. Peterson and Dr. Densley’s innovative crisis response training program, we experienced a 23% decrease in crisis related service calls in our first year. Officers reported that the training was one of the best they have had, providing realistic tools they can use when helping those in crisis.
The nightmare scenario for a principal related to safety is a school shooter. Dr. Peterson and Dr. Densely’s research on mass shootings, and most importantly their framework for how we can think about prevention, provides school and system leaders with research that can be trusted and used in practical ways.
Teachers are on the "front lines" when it comes to recognizing students who are facing crisis. Teachers deserve a "real world tool box" to support a student who reaches out to them for help. Mass Shooting Prevention Training provides this "tool box." As a former educator and now, a survivor of a school shooting, I know how important it is for teachers to be able to "do something" when a student asks for help. Mass Shooting Prevention Training provides this help.
