Welcome to Critical Intervention Services

Since 1992, Critical Intervention Services (CIS) has assisted hundreds of clients in managing a diverse range of security risks.

In many cases, our mission is accomplishing through expert application of classic security and public safety measures. Our consultants regularly assist clients with matters such as security risk assessment, physical security design, emergency response planning, expert witness testimony, threat assessment, executive protection, and other services within the scope of well-established doctrine.

Although our team is well recognized for their expertise, knowledge is only one facet of our reputation.

Over the past three decades, CIS has earned unique recognition for achieving success in situations where traditional approaches to security and public safety have failed. When addressing complex and difficult security challenges, knowledge alone is often insufficient. Effective solutions often require an artful combination of expertise, holistic vision, and innovative mindset.

Over the years, CIS clients have provided us the opportunity to apply our talents to a diverse range of challenges—urban crime and social disorder, terrorism, school violence, and more. And we are honored that the unique risk management strategies produced from our experience have been endorsed as best practice standards by professional peers, news media, and academic researchers around the world.

Regardless of the complexity of the situation, effectiveness and excellence are the core principles founding our philosophy and approach to client needs. Although all consulting firms promise excellence, at Critical Intervention Services the pursuit of excellence isn’t just a pledge. It’s the lifeblood of our culture and the cornerstone of our success as proven for nearly thirty years.

Thank you for your interest in Critical Intervention Services. We are honored to serve you.
