Active Shooter Prevention Experts

The ASPP™ Community of Experts

No single firm has every capability a prevention program needs, and the ones that claim otherwise are describing a sales sheet rather than a problem. Active shooter prevention experts earn that title in one discipline at a time. Preventing targeted violence touches behavior, buildings, technology, policy, law, medicine and command, and nobody is credible in all of it.

So we built the Community of Experts instead. It is a standing group of active shooter prevention experts who bring depth we do not have on our own, and who can be brought into an engagement when the work genuinely calls for them.

Members of the ASPP Community of Experts, active shooter prevention experts from law enforcement, defense, security technology and school safety, gathered for a group portrait — The Community of Experts. Independent practitioners who keep their own firms and their own opinions.

What it is, and what it is not

**Table 1.** Community of Experts, structure and boundaries
It is	It is not
Practitioners with operational records in their own field	A referral network or a directory of vendors
Brought in when an engagement genuinely needs that discipline	Attached to every proposal to inflate a team page ^a
Named publicly, with their own profile, at their own consent	A logo wall of people who once took a meeting
Independent. They keep their own firms, their own work, their own views	Employees, resellers, or a channel we take a cut of ^b

^a A capability listed on a proposal that does not appear on the engagement is a misrepresentation. We would rather have a shorter list.
^b Independence is the reason their assessment is worth anything. A recommendation from someone earning a commission on the answer is not an assessment.

The disciplines our active shooter prevention experts cover

The roster spans federal and local law enforcement, behavioral analysis, military and defense leadership, physical security and venue operations, detection and security technology, emergency communication, school safety, healthcare and corporate risk, and legal and policy work. Some are retired flag officers. Some run their own security firms. Some spent careers inside agencies whose names you would recognize.

These are working practitioners rather than advisers on paper. Every one of the active shooter prevention experts listed has a published profile. We do not list capabilities we cannot put a name and a face to. See the full Community of Experts roster.

Why independence is the whole point

Independence is why we call them active shooter prevention experts rather than staff. An expert who works for us tells you what we think. An expert who does not tells you what they think, which is the only version worth paying for. Community of Experts members keep their own companies and their own opinions, and more than once that has meant somebody in this group telling a client that the thing we proposed was not the thing they needed.

That is a feature. It is also why we can say we sell no hardware, hold no reseller agreements and take no commission, and have it mean something. Independence that costs nothing is not independence.

How members come in

Slowly. Somebody in the group vouches, the work gets checked, and nothing goes public until the person has agreed in writing to how they are described. Chris Grollnek, Chairman of the Board & Founding Principal, approves every listing, and titles are confirmed with the individual rather than assumed from a LinkedIn headline.

That process is deliberately slow because the alternative is a page full of names that impress until somebody calls one of them.
