On behalf of the entire Threat Suppression team, I would like to cordially introduce you to our company! Threat Suppression was formed in 2012 when four people recognized the need for high quality safety and security consulting. The four founders were all members of a Special Weapons and Tactics (SWAT) team with a large law enforcement agency. Collectively, the founders brought more than 125 years of dedicated public safety experience to the company. Threat Suppression has continued to grow, adding many more employees, all who have recognized specialties in public safety. Our team has more than 500 years' experience in public safety with response to more than half of a million emergency calls. 


From our inception, we have worked to recruit extremely talented experts in the safety and security field. Our staff are incredibly accomplished individuals. I encourage you to check out their biographies by clicking here. I am deeply honored to work with each of these individuals. Our greatest company strength is – and always will be – our employees.
