He brings a wealth of knowledge from his time in the Marine Corps, Law Enforcement, and the Private Sector, where he has provided strategic advisory services to top executives in the country.
Following his involvement in the Active Shooter Event in McKinney, Texas in 2010, Chris redirected his post-graduate studies and wrote his thesis on the phenomenon of active shooter events. He then began contracting with the Department of Homeland Security and wrote and appeared in a documentary about active shooter incidents and survival guidance. Chris is one of the only security professionals in the country with both personal experience in a domestic terrorism event and a master’s degree in the field, making his expertise truly unique.
Chris founded the Active Shooter Prevention Project (ASPP™), LLC which uses a multi-faceted approach to offer comprehensive solutions from a broad spectrum of partners and is focused on preventing incidents before they occur. As the Chairman of the Board & Founding Principal and Founder of the Active Shooter Prevention Project, Chris and the team of “Community of Experts” he established are working to make the P.R.O. Model™ (Prevention. Response. Options.) a national standard of Active Shooter Prevention for the public and emergency responders which has been adopted by several agencies and departments within the US Government.
As the creator of the P.R.O. Model™, an “A” DOJ-selected national standard for active shooter prevention, Chris was hand-selected by several US Government agencies to create and film active shooter prevention training videos. The most recently released video was purpose-built, written, and designed by Chris Grollnek with the intention of training the Executive Offices of the United States Attorney. It has been made available to the entire Department of Justice for their semi-annual Active Shooter training requirement.
Chris is an expert on the prevention of and response to the active shooter phenomenon; the U.S. Army has called him “one of the country’s foremost authorities on active shooters” (army.mil, 8 October 2024). As one of just a few legacy experts with active shooter experience, Chris’ expertise is in high demand across the nation and across industries. Chris provides strategic advisory services for the highest levels of government and the most senior executives in the country. He’s also retained by families seeking criminal and financial restitution for the loss of loved ones during an active shooter event.
Grollnek has appeared on numerous national television networks, including Fox, CNN, MSNBC, Fox Nation, Fox Business, OANN, ABC, CBS, NBC, BBC, and numerous syndicated radio broadcast programs.
