David Skeen
Head of School

We recently contracted with Defend Systems to work with our faculty around active shooter and active shooter preparation for all 83 full-time faculty and staff on campus.

Defend Systems came prepared for our institution and our faculty and our campus and gave our faculty the sense of competency that they really thirsted for in a situation where they're really gonna need it because it's gonna save lives.

Schools and campuses
Dan Dustin
President & CEO

We recently brought in Defend Systems to provide active shooter training. We opened the staff training to everybody who wanted to sign up. It was a great opportunity for individuals in our company to understand what to do if an unfortunate event occurred in the future.

Corporate
Will Kesler
Head of School

The biggest barrier when you’re thinking about training for faculty is making a decision on return on investment. What I would say as a Head of School is that these are some of the best dollars we have ever spent in terms of professional development for our faculty and staff.

Schools and campuses
Sean O'Brien
Associate Vice Chancellor for Public Safety and Chief of Police

Our employees were not prepared and did not have an understanding of how they should respond in that event. And that is ultimately why we partner with Defend Systems—to empower our employees to understand how to respond to these events and give them skill sets that they wouldn't otherwise have.

Schools and campuses
Alyssa Erwin
Security - Global Tech

Going into the training, the medical part of it was probably what I was the most nervous about. But it really is a life skill. Whether it is, god forbid, an active shooter event or even just an unfortunate accident that you happen upon, like I genuinely do feel I would be prepared and able to stay calm and help someone in the event that I needed to.

Corporate
Diana Couey
Registered Nurse

I have been a nurse for over a decade. I've received all kinds of medical training and worked in all kinds of different settings, but the trauma and medical first responder training that we received in this program was incredible, and really taught not just me but all of my co-workers who don't have a medical background that any of us could be a first responder in an emergency situation.

Schools and campuses
Abby McLean
Director of Children’s Ministry

We value every single person in this church. We value their life. The benefit, financially, for bringing someone like Brink to any business, any church, any school—is priceless.

Church
Jim McIntyre
Former President

We partnered with Defend Systems to not only talk to us about how you deal with a crisis on campus but more importantly how to respond to circumstances.

Schools and campuses
Virginia Schmidt
VP of Human Resources

If you are looking for a company that can help you and your employees to prepare for the unthinkable…a shooter in your facility, look no further. Defend Systems is that company. Brink Fidler met with our management to explain the core methods of training and education that Defend Systems provides. Brink conducted a thorough walk through of our facility, both office and warehouse, to identify areas of concern or vulnerability. He provided corrective suggestions and praised us for the safety measures that were already in place.
