Corey Gephart

CEO, St. Luke’s Community House

They made recommendations for building improvements, trained our staff on safety and medical response techniques, and helped us choose other vendors to make our organization safe. We could not have done this with just any consultant. I cannot recommend Defend Systems highly enough. If you are responsible for the safety and security of some of our most vulnerable people, you shouldn’t wait to call Defend Systems.


Kate Riley

Head of School, Holy Trinity Montessori

Defend Systems was an amazing resource to our school, Holy Trinity Montessori, as we built and designed our new campus. They are extremely knowledgeable in their expertise of safety, school trauma and emergency awareness. In this day and age, schools must live in a very different time of awareness and safety and having Defend Systems as a resource has been invaluable.

As we designed our new campus, we looked at all issues of intrusion, school shooting and school emergencies. The team at Defend Systems was able to advise us in this journey as seen in our design process with the architecture firm. I would recommend Defend Systems and their expertise in any emergency situation consulting. We have enjoyed working with them and look forward to working with them in the future.


Jennifer Potts

Human Resources Manager

As an employer, the safety and security of our employees is always top priority. With the most recent events involving armed assaults on businesses and schools, we believed it was of the upmost importance to prepare our team of employees for this type of horrific event. Our experience with Defend Systems and Brink Fidler was impeccable. Brink came out and personally did a walk through with me of our entire facility and we discussed areas of concern that could increase the possibilities of a breach in our building security. Brink shared with us what we were already doing right and what we could improve upon. Brink then prepared our training and came out to our facility to perform both classroom and live fire training.

Best presentation I have ever seen!!!
Every company and school needs to see this preso!


Kaitlynn Whiteaker

Great training, we no doubt need these in all schools.

However, there needs to be an opportunity for those sensitive to videos about gun violence to leave the room before they play. I know the videos get the point across, but some people have panic attacks because of those kinda of videos.

Brian Sweatt

Brink and his team at Defend Systems did an amazing job during their recent training of our teachers at Lighthouse Christian School. The training was informative, clear and practical. If you need someone to help you and your team be prepared in a crisis or emergency event, Defend Systems would do an incredible job!


Kristy Noel Morgan

I was lucky enough to be able to participate in an active shooter class today. I learned so much. Everyone needs to take this class.


Karina Hammer

Executive Director, Bellevue Home School Enrichment & Tutorials

I highly recommend any business, school, church or private home to have Defend Systems do a walk through to see how you can improve the safety of your employees, congregation or family.

Brink walked through our church facility to see how we can keep our homeschool students safe during our one-day-per-week program. Then, he gave the tutors a training with practical strategies on how to prevent and respond to an active shooter situation.


David Glascoe

Executive Director, Mary Queen of Angels, Assisted Living Community

Thanks so much for your excellent work which will help us provide better security for the residents and associates at Villa Maria Manor and Mary, Queen of Angels. I believe your approach to this challenge shows your experience and is unlike what we learned from other resources. You offered practical solutions that will help us convey that we are not a soft target. It feels good to be acting proactively to make it difficult for those who would do us harm. Great job!


Kim Haley

Operations Manager, Renewal House

Defend Systems provided an exceptional training for our staff that was relevant to our facility and our specific needs. Renewal House provides specialized addiction treatment to women and their children in a campus environment. We learned many tips and techniques to prepare us for any situation. The site assessment helped us identify areas for improvement and the recommendations they provided are sound and completely attainable. We are grateful for the services they provided and look forward to a continued relationship.

Cindy Ligon

Director of Early Childhood Education, McKendree United Methodist Church, Nashville, TN

As the director of an early childhood program, health and safety is a high priority, especially given America’s gun violence epidemic. We are grateful for the work of Brink Fidler and Defend Systems. They assessed our existing emergency plan and gave us thoughtful recommendations for security upgrades. 


Melanie Anderson

Director of Education, High Hopes Development Center

Defend Systems has been invaluable to our organization. They helped us identify security issues and consulted with us on how to create and implement (if ever necessary) an emergency plan that keeps everyone as safe as possible. When we began planning our move to our current facility, they helped us by identifying areas that needed to be more secure and suggested ways to make it happen. They not only consulted with us, but also provided training for staff members. 


Amelia Baldwin

Chief Operating Officer, Onsite Workshops

We appreciate and admire Brink Fidler and “Defend Systems” passion and commitment to providing the training and “action planning” to our company that is so necessary and relevant to today’s world. Not only did they provide a customized, site specific, emergency response protocol, as well as emergency medical response training, but also referred and collaborated with other resources to provide additional physical security analysis and enhanced safety measures. In addition to the excellent training and security enhancements, we were also provided “in-house” training materials for new staff members. Thanks Brink and the “Defend Systems” team for your expertise and professional security services!


Virginia Schmidt

VP of Human Resources JPW Industries, Inc.

If you are looking for a company that can help you and your employees to prepare for the unthinkable…………. an armed shooter in your facility, look no further. Defend Systems is that company.

Brink Fidler met with our management to explain what 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.


Dana Reno
