John Krewer is the Founder and Chief Executive Officer of Integrity Security Services. Originally from Monmouth County, New Jersey, Krewer began his career in law enforcement at the age of 19 where he served 16 years with the Philadelphia Police Department.

Krewer spent the last nine years of his law enforcement career as a Federal Bureau of Investigation Task Force Officer, working alongside federal agents investigating violent crime and organized criminal enterprises. His work included cases involving homicide, murder-for-hire plots, Hobbs Act robberies, and complex RICO investigations.

Following his law enforcement career, Krewer founded Integrity Security Services with the mission of bringing government-level protection to the private sector. Krewer maintains a hands-on leadership approach with Integrity’s clients. Rather than routing communication through account managers, clients have direct access to him. He believes the highest level of protection requires accountability, trust, and direct communication. Integrity Security Services is the only security firm operating in both New Jersey and Pennsylvania that exclusively employs active and recently retired law enforcement officers.

Krewer holds a Bachelor’s Degree in Public Safety Administration from Neumann University and currently pursuing a Master’s Degree in Security Management from John Jay College of Criminal Justice. Krewer is also a 6ABC News Contributor and a member of the Vidocq Society, an organization that provides pro bono assistance to law enforcement agencies working to solve cold case homicides.
