When I attended the opening of the Active Shooter Response Training Center (ASRTC), I was instantly hooked; both to it and Jimmy Graham.  I achieved the Able Shepherd rating 14 months later.  I’m amazed that I was able to accomplish this, and I still hold the record for being the oldest to do it.  While I have always felt a great need to provide for and protect my loved ones, I never knew I could attain such skills to assist me in this endeavor.  After finishing a 38-year career as an executive in construction, it is my honor to be the COO of this program.

The Facility

Our facility includes a training classroom, open training floor, simulation room, live-fire multi-lane shooting range & a debriefing lounge. We also regularly utilize off-site venues to further enhance your response skills and capabilities.

Training Classroom

Our large training classroom is equipped with projector and sound giving us the ability to benefit from presentations, real-world video clips, and online references to aid our instruction and discussions.

Open Training Floor

Our large open training floor provides us with enough room to get on our feet and perform the drills necessary to learn skills in a manner that is fun and effective.

Designated Simulation Room

In our Simulation room we can specifically design realistic scenarios to validate the skills learned that day. Students will engage real people with non-lethal training rounds to demonstrate split second Shoot or No-Shoot responses.

Designated Live-Fire Multi-Lane Shooting Range

Our 6 lane, indoor, Live-Fire shooting range is equipped with programmable turning targets allowing us to train year-round, rain, snow or shine.

Debriefing Lounge

The Debriefing Lounge provides us with a location to unwind and discuss lessons learned after an “exciting” experience in a scenario. Any mistakes are respectfully addressed for future correction and successes are reinforced for retention. The only way we get better is to honestly evaluate our capabilities, strengths and weaknesses in training… and then improve them for ‘what if’ situations in the future.
