What is the Able Shepherd program?

Able Shepherd™ is the standard-setting, nationally-recognized progressive tactical training program in Denver, Colorado, designed to teach situational awareness, leadership, first aid and protective tactics that can be applied to virtually any threatened environment. We operate from the belief that your family’s immediate safety cannot be delegated; you can be the fastest and most capable ‘first responder’ in your immediate vicinity.

At its core, Able Shepherd™ is an elite-level self-defense program utilizing armed and unarmed tactics. Graduates become known as “Able Shepherds,” gaining skills that empower themselves to actively protect, guide and strengthen their communities. Our goal is to make you, and those around you, safer. We do this by holding you to the highest of moral, ethical and tactical standards.



Show Respect; Be nobly worthy of respect.



Steadfastly adhere to a strict moral or ethical code.



Start with yourself, and grow outward.

“Able Shepherd is a progressive training program designed to empower members to protect, guide and strengthen their communities. The motto is “Take Care of One Another”. Some of the best parts of the SEAL Teams that I greatly miss (brotherhood, camaraderie, accountability…), I have found again with my buddies here at home in the Able Shepherd Program.”

What is Reality Based Training?

In this video, Able Shepherd CEO and Founder Jimmy Graham explains the importance of real-life scenario-based live-action training. Using our advanced shoothouse, Simunition rounds and trained roleplayers, our reality-based training program is as real as it gets!

What is a Dynamic Live Range?

Jimmy Graham, CEO and Founder of the Able Shepherd program, shares why the ability to move, or go ‘dynamic’ within a range is paramount to proper training. Our team of Dynamic Range Safety Officers ensure that your training ‘downrange’ is upheld with the highest standards of safety and care.

Our Facilities

Our facilities include training classrooms, open training floors, simulation rooms, a 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.

Our Team

All of our instructors are Able Shepherd Certified, Dynamic Range Safety Officers, CPR/AED First Aid Certified, and are held to the highest standards of proficiency through regular testing and recertification.

Proud parent to our son Alex who is currently serving in the United State Marine Corps.  Favorite story includes Alex on a live range with a Marine Corps Drill Sergeant ‘asking’ him where he learned to shoot a rifle 3 and 3 like that (so fast) to which my son proudly responded .. My Dad .. Sir.  Thank you to Jimmy, Parker, and all the Instructors for providing the skills, drills, and training to share with our son.
