Window Film Depot named Krissy Mosby its President, leading a national provider of security window film and retrofit glazing for schools, government buildings, and commercial facilities. Retrofit is the honest answer for the overwhelming majority of buildings, because they already exist and nobody is rebuilding them. ASPP™ was founded by Chris Grollnek, an active shooter expert whose P.R.O. Model™ the Department of Justice selected as “A” national standard and which is in use at some installations and commands across the Department of Defense.

Real Stories from Those Who’ve Experienced ASPP PRO’s Impact

Chris, I’m the FBI’s program manager for active shooter situations and on the White House working group seeking ways to prevent gun violence. I wanted to drop a note and let you know that I thought the DOJ video was well done. You address many points that we have been stressing.

I worked with Chris on a case covering several months and found him to be most diligent in handling the requirements of the project from inception to completion. He was always quick to respond to requests for information and assistance and his work product was invaluable to the successful outcome of the case. Chris is very goal oriented and was flexible to employ the necessary tactics and strategies to achieve the goals we had set for the project.

Chris, thanks so much for those kind words. I know my staff is very grateful for your insights and advice on keeping PCM a little safer. I can see God has given you a real calling in this area, and I encourage you to keep at it. At the end of your career, when you are looking back at everything, knowing you did what God called you to do will be worth more than you know. Take this advice from someone on that side of the river! Many blessings to you and safe travels!

I first met Chris Grollnek after the Pulse Nightclub massacre. He’s extremely knowledgeable about best practices regarding active shooters. Chris took great pains to explain law enforcement’s failures when responding to Pulse. He doesn’t talk down to ordinary citizens. Rather, he converses in a manner the layperson can comprehend. I’m very grateful for my professional relationship with Chris Grollnek.

Thank you for presenting at the People’s City Mission on December 10th. Your presentation was greatly appreciated, and I have already shared some of the valuable information you provided with my organization. Your storytelling approach was engaging, although it would have been helpful to know more about the audience’s background and why we were all there. It’s a shame more people couldn’t attend, as your message deserves to be heard by a wider audience. Best of luck in your mission to raise awareness and put an end to these events.
